Dockerfile build - possible to ignore error?
Sure. Docker is just responding to the error codes returned by the RUN shell scripts in the Dockerfile. If your Dockerfile has something like: RUN make You could replace that with: RUN make; exit 0 This will always return a 0 (success) exit code. The disadvantage here is that your...
How to tag Docker images with a Git tag in Jenkins?
git,jenkins,docker,jenkins-plugins
After taking another look at the problem with a clearer head, I found a simple solution to this problem in scripting the creation a temporary properties file with my git tag and using Envinject's "Inject environment variables" build step to read that file. My final configuration looked somewhat like this:...
Hide/obfuscate environmental parameters in docker
you say "Alternatively, is it possible to pass sensitive parameters by reference to a file?" , extract from the doc http://docs.docker.com/reference/commandline/cli/#run --env-file=[] Read in a file of environment variables
Automatic building and installing Packages from AUR for Arch Linux inside Docker with yaourt and >makepkg-4.2.0

Commit data in a mysql container
mysql,linux,database,docker,virtualization
The official mysql image stores data in a volume. Normally this is desired so that your data can persist beyond the life span of your container, but data volumes bypass the Union File System and are not committed to the image. You can accomplish what you're trying to do by...
Vagrant + puppet + docker
I would skip Vagrant step. Docker containers are enough in most cases. Ad. 2. Of course you can create separate containers for each instance and app (e.g. one for server app, one for database and one for some queue). You manage dependencies between containers using link command (read here). To...
What tool can manage Docker container to start in order?
The simplest approach that works would be to simply add a retry policy to your container and make sure that if it cannot access the required resource on startup it exits: docker run -d mysql docker run -d --restart always --link mysql:mysql nginx start_or_die.sh The start_or_die.sh script here would first...
Docker Data Volume Container - Can I share across swarm
docker,large-data-volumes,docker-swarm
Can data volume containers be used/mounted in containers residing on other hosts within a docker swarm? Docker, by itself, does not provide any facility for either migrating data or sharing data between hosts in a cluster. How is the performance? is it recommended to structure things this way? Docker...
When should you create more than one docker container image instance with Kubernetes Replication Controller?
docker,google-compute-engine,kubernetes
I think you laid out the issues pretty well. The two kinds of scaling you described are called "vertical scaling" (increasing memory or CPU of a single instance) and "horizontal scaling" (increasing number of instances). On availability: As you observed, you can achieve pretty good availability even with a single...
How to inspect a docker image in docker hub?
As per the docker hub documentation - Docker itself provides access to Docker Hub services via the docker search, pull, login, and push commands. It does not look like you can do a docker inspect without pulling one image...
How to find the name of intermediate Docker images?
These images are the intermediate layers that make up other images. Each instruction in a Dockerfile results in a new image being created. A lot of Dockerfile instructions only result in changes to the "metadata" rather than the filesystem (e.g EXPOSE, MAINTAINER) which accounts for images with the same size....
Docker ignores iptable rules when using “-p :”
Your iptables configuration looks a little broken right now, as if you cleared it out at some point without restarting Docker. For example, you have a DOCKER chain available in both the filter and nat tables, but no rules that reference it, so rules placed in that chain will have...
Configure Dockerfile to set AWS configurations
node.js,amazon-web-services,docker
I think the answers regarding the environment variables are good solutions. To offer an alternative, or if you use a file for aws authentication, you could use docker volumes to mount these. Mount a Host Directory as a Data Volume In addition to creating a volume using the -v flag...
Not able to clone private repo using dockerfile

docker run python from container
How do I use the python interpreter from the container without having to type docker exec everytime? What about opening a shell in that container instead? docker exec -it <your container id> /bin/bash -l and then from there use python. Also, how do I access the project code in...
Docker container returns “unknown” for “uname -p” command
I don't know the exact reason why uname -p fail with the java:7 docker image but it seems to be due to the docker debian image. With the ubuntu docker image, everything is fine. $ docker run debian uname -p unknown $ docker run ubuntu uname -p x86_64 If you...
Mount Github link as docker volume
You cannot mount such remote resources that are on the Internet. What you can do is to have a shell script in your docker image which when executed will download those resources. And make docker run that script when the container is run. Dockerfile FROM ubuntu:latest COPY download-from-github.sh / #...
docker networking - Could not discover any bindable network interfaces
linux,osx,networking,docker,boot2docker

Is docker must run under linux 64bits?
Now docker only supports amd64 architecture. According to this post, docker developers will eventually provide support for other architectures, https://github.com/docker/docker/issues/136....
“Dockerized” apps frequently are built on top of OS containers. Why doesn't this defeat the purpose?
A Docker image (which will most likely contain the base system from a Linux distribution), is read only and is augmented with several layers that are enabled as you write to a location. So you can share the base image and have "add-ons" if you will. This is called a...
Disable ip v6 in docker container
Unfortunately there isn't: --ipv6 is a daemon-wide flag that cannot be overridden on a per-container basis.
Difficulty accessing Docker's API
I figured it must be a firewall problem but it took a while longer before I realised it was the firewall built into Linux. To make 2375 accessable: Use one of the following depending on your distro sudo firewall-cmd --zone=public --add-port=2375/tcp --permanent sudo firewall-cmd --reload OR sudo iptables -I INPUT...
Use of container docker as a proxy for CF app to get public IP
No you can not do this. The DEA's (part of Cloud Foundry that runs your app) is firewalled off from talking to internal IP's of other DEA's. In Bluemix we do not charge for network bandwidth.
Kubernetes minion not completely connecting
docker,coreos,kubernetes,etcd,flannel
Currently, I have to manually register the minion prior to spinning up the minion instance. This is because there is an open issue as of right now not allowing the minion to self-register in certain cases. UPDATE Now I'm using kube-register to register each minion/node on start of the kubelet...
Access other containers of a pod in Kubernetes
All the containers in a pod are bound to the same network namespace. This means that (a) they all have the same ip address and (b) that localhost is the same across all the containers. In other words, if you have Apache running in one container in a pod and...
Why does single-user with heredocs and multiline queries throw syntax errors for postgres+docker?
When using the postgres binary to submit SQL commands (as opposed to psql), the end-of-line is the end of the command and the semi-colon has no meaning. Per documentation: Normally, the single-user mode server treats newline as the command entry terminator; there is no intelligence about semicolons, as there is...
Why are images created and why doesn't Docker clean them up?
Every RUN line in a Dockerfile is essentially equivalent to docker runing the previous line's image. By default docker keeps all these intermediate images to help with caching, this speeds up subsequent builds. You can ask them to be removed when building by specifying the --rm or --force-rm flags.
Adding nodes on the fly with Docker Swarm
Not you can't add on the fly nodes with list of IPs without restart manually your swarm and adding new hosts. But if you use swarm with service discovery you can do it. You can found here the needed reference to implement docker-swarm with service discovery and how join nodes...
Why is /etc/hosts file empty in my docker container?

Running quick programs inside a docker container
This sounds like a good candidate for a microservice, a long-lived server (implemented in your language of choice) listening on a port for resizing requests that uses graphicsmagick under the hood. Pros: Implementation details of the resizer are kept inside the container. Scalability - you can spin up more containers...
What does docker use for (image) versioning?
Docker doesn't internally use git today for any kind of resource versioning. It does however: Rely on hashing to uniquely identify the file system layers: this is what can make it resemble git to the user Take initial inspiration in the notion of commit, pushes and pulls One thing that...
How to mount volume for docker container via yaml manifest?

Use Dokku Environment variables in DockerFile
docker,environment-variables,dockerfile,dokku
I've never used Dokku, but you will only be able to use those variables at run-time in a launched container. Docker intentionally doesn't allow you to pass in variables to docker build, so that builds are reproducible across environments. I suspect you can just write a script that configures the...
AWS EC2 Container Service / Elastic Beanstalk Docker Container Port udp binding

How to Setup a Docker Tomcat Container on Mac OS X
Information: Because Docker only runs on Linux you will need to install some kind of virtual instance on your local machine. An easy and popular way to do that is to install Boot2docker and VirtualBox. VirtualBox is a dependency of Boot2docker. You can download, setup and install the latest versions...
Server and client network apps simulated in one machine
Yes. With linking containers, exposing and publishing[publish ports containers can communicate with each other or with the host machine.
Passing Elasticsearch and Kibana config file to docker containers
elasticsearch,docker,kibana,kibana-4
Can I do that with this image itself? yes, just use Docker volumes to pass in your own config files Let say you have the following files on your docker host: /home/liv2hak/elasticsearch.yml /home/liv2hak/kibana.yml you can then start your container with: docker run -d --name kibana -p 5601:5601 -p 9200:9200...
ldapadd gives “no global superior knowledge” on default config
You seem to have named the root of your LDAP DIT as dc=myorga. So an entry that requires ou=users,DC=example.com isn't going to work. You'll have to change that accordingly.
What is the '.save_docker/' folder? Can I delete it?
save_docker doesn't seem used in docker or boot2docker or compose or machine. But even before trying to remove it, check if you have: stopped containers that you could remove docker rm -v $(docker ps -a -q -f status=exited) dangling images docker rmi $(docker images --filter "dangling=true" -q --no-trunc) For that,...
difference between docker attach and docker exec
There was a commit PR which added to the doc: Note: This command (attach) is not for running a new process in a container. See: docker exec. The answer to "Docker. How to get bash\ssh inside runned container (run -d)?" illustrates the difference: (docker >= 1.3) If we use docker...
Where is my Docker Wordpress Website Storing Data?
When you run wordpress container for the first time, the initialization script downloads the wordpress codebase to /var/www/html and then start the web server. Since everything inside a container is ephemeral, the codebase with any changes you make will be lost when you re-run the container (unless you just stop/start...
Where does kubernete's kubelet create service environment variables?
node.js,docker,service-discovery,kubernetes
The environment variables for a given service are put in every container that is started after the service was created. For example, if you create a pod foo and then later a service bar, the pod's containers won't have any environment variables for bar. If you instead create service bar...
Strategy to persist the node's data for dynamic Elasticsearch clusters
elasticsearch,docker,mesos,marathon
Elasticsearch and NFS are not the best of pals ;-). You don't want to run your cluster on NFS, it's much too slow and Elasticsearch works better when the speed of the storage is better. If you introduce the network in this equation you'll get into trouble. I have no...
Simple docker deployment tactics
I do both. My Dockerfile checks out the code for the application from Git. During development I mount a volume over the top of this folder with the version of the code I'm working on. When I'm ready to deploy to production, I just check into Git and re-build the...
Unable to get docker containers running disque to establish a cluster
The problem should be due to the fact that Docker uses port forwarding, which is not compatible with the way Disque works currently. However you can disable port forwarding in Docker using a 1:1 mapping, with something like this: $ docker run -d -p 7711:7711 ... When this will be...
Golang failes to change the name of imported module
The Go compiler doesn't replace or rewrite anything, the code is just wrong. The github.com/rcrowley/go-metrics/influxdb package was written with some other influxdb client code that no longer exists. (Looks like there are a couple github issues open about this already) If you look at the current influxdb/client package, you'll see...
docker-compose error - unable to read file
The docker build executes in a container separate from your host. The container has its own filesystem and is unaware of files on the host system. You may copy files to the container by using COPY /path/on/host /path/on/container in the Dockerfile Currently pip needs files, but they have not been...
Docker Wordpress Container Exits after ~30 seconds
I have found the solution. Docker offers two networking modes: bridge, and host. The bridge networking mode is default, and when using this mode, MySQL must be listening for connections on the Docker host IP address (172.17.42.1). In other words, the bind-address in the MySQL config file must be set...
Docker, no IPAddress in docker inspect
Looks like you need to run boot2docker ip and use that
Run Boot2Docker from bash
Replace your boot2docker start with boot2docker start && $(boot2docker shellinit) and you are good to go. $(boot2docker shellinit) will export all the Environment variables needed.
docker run local script without host volumes
database,shell,docker,docker-compose
The solutions I have found are: docker run tomdavidson/initdb bash -c "`cat initdb.sh`" and Set an ENV VAR equal to your script and set up your Docker image to run the script (of course one can ADD/COPY and use host volumes but that is not this question), for example: docker...
Access binaries inside docker
It doesn't seem to be configurable at the moment based on this open issue. However, you could always fork the project and modify the start script to use your own custom docker image. If so, make sure you make it: FROM meteorhacks/meteord:base ...
Docker inspect with unix:///var/run/docker.sock (in Java or Scala)
It's not possible to use pure java as there is no framework support for Unix sockets. However, you can use some sort of jni-library for this. Like this one.
Moving Docker Containers Around
The first rule of Docker containers is don't locate your data inside your application container. Data that needs to persist beyond the lifetime of the container should be stored in a Docker "volume", either mounted from a host directory or from a data-only container. If you want to be able...
Ensure nginx master process stays running
You need to append daemon off; to your nginx.conf configuration instructing nginx to run in the foreground. Then modify your supervisor stanza to be: [program:nginx] command=nginx autorestart=true It will still spawn master/worker processes/subprocesses and can be used this way in production setups just fine. In this case it's supervisor that...
Docker: understanding ENTRYPOINT and CMD instructions

docker-machine without TLS verification
docker,boot2docker,docker-machine
After some research about it and interchange with other user over freenode chat room, I found that in current version this option is not available, you can't set env var to disable TLS verification on creation process with docker-machine. Also some people recommend for now use solution presented on deis/issues/2230.
How can I create a docker image from the current system?
google-app-engine,docker,boot2docker
You can SSH into the Container, make changes and then you can commit the container, which will save your changes to an image. You can now push this image to registry. Unless you are using a data container, all your changes are saved.

docker set iptables options in docker-compose.yml
The --iptables option only applies to the Docker daemon; it's not a per-container option. The corollary is that this isn't something you could ever set from your docker-compose.yaml file. You would need to modify the options passed to the Docker daemon; on Red Hat systems and derivatives this means you...
How to see a linked container as localhost?
There seems to be some confusion here. It looks like you are trying to log into the web container and access the api container using the localhost address? This isn't going to work. The best solution is just to use the link you've declared; within the web container you should...
How to properly set VOLUME and CMD instructions in Postgres Dockerfile?
I'm not sure about the first problem. It may be that Postgres doesn't like running on top of the UFS. The second problem is just that a container will exit when its main process ends. So the command "service postgres start" runs, starts Postgres in the background then immediately exits...

Okay so to answer your question(s): In PyCharm, I can set a remote python interpreter via SSH but I'm not sure how to do it for dockers that can only be accessed via Boot2Docker? You need: To ensure that you have SSH running in your container There are many base...
Docker container http requests limit
So, it wasn't a problem with either Docker or Elastic. Just to recap, the same script throwning PUT requests at a Elasticsearch setup locally worked, but when throwning at a container with Elasticsearch failed after a few thousand documents (20k). To note that the overal number of documents was roughtly...
docker is using the v1 registry api when it should use v2
You need to secure the registry before you can access it remotely, or explicitly allow all your Docker daemons to access insecure registries. To secure the registry the easiest choice is to buy an SSL certificate for your server, but you can also self-sign the certificate and distribute to clients....
How to customize the configuration file of the official PostgreSQL docker image?
The postgres:9.4 image you've inherited from declares a volume at /var/lib/postgresql/data. This essentially means you can can't copy any files to that path in your image; the changes will be discarded. You have a few choices: You could just add your own configuration file as a volume at run-time with...

Any suggestion for running Aerospike on Kubernetes on CoreOS on GCE?
docker,google-compute-engine,kubernetes,aerospike
An alternative to specifying all mesh seed IP addresses is to use the asinfo tip command. Please see: http://www.aerospike.com/docs/reference/info/#tip the tip command asinfo -v 'tip:host=172.16.121.138;port=3002' The above command could be added to a script or orchestration tool with correct ips. You may also find addtional info on the aerospike Forum:...
Accessing files inside Docker container
The best way would be to use VOLUME and mount your source codes to the container. That way, your IDE will have access to code in the host and all the changes you make will also be reflected in the containers.
How to pull private docker image from docker to new machine
You need to run docker login before you can access private repositories.
Saving docker container image
Data in a Docker volume (such as /var/jenkins_home) is not preserved as part of the docker commit operation. This is intentional -- the idea is that you are persisting you data via some other mechanism, such as a host volume (-v /host/directory:/var/jenkins_home) or through the use of a data container...

Not able to access Kibana running in a Docker container on port 5601
elasticsearch,docker,dockerfile,kibana-4
The parent Dockerfile devdb/kibana is using a script to start kibana and elasticsearch when the docker container is started. See CMD ["/sbin/my_init"] and the script itself. When in your own Dockerfile you use the CMD instruction, you override the one from the parents Dockerfiles. Since your CMD only starts gunicorn,...
Docker: how to set up file ownership in a data-only container?
