git.io/dockerhub

Contains 50+ DockerHub repos with 340+ tags, many different versions of standard official open source software, see Full Inventory futher down

These docker images are tested by hundreds of tools and also used in the full functional test suites of various other GitHub repos.

See also the Kubernetes configs repo.

Overview - this repo contains:

These images are all available pre-built on My DockerHub - https://hub.docker.com/u/harisekhon/.

These are reusable tests that can anybody can implement and can be found in my DevOps Python Tools and DevOps Bash Tools repos as well as the Advanced Nagios Plugins Collection which contains hundreds of technology specific API-level test programs to ensure the docker images are functioning as intended.

Continuous Integration in run on this and adjacent repos that form a bi-directional validation between these docker images and several other repositories full of hundreds of programs. All of this is intended to keep the quality of this repo as high as possible.

Ready to run Docker images

docker search harisekhon
docker run harisekhon/nagios-plugins

To see more than the 25 DockerHub repos limited by docker search (docker issue 23055) I wrote dockerhub_search.py using the DockerHub API, available in my DevOps Python Tools github repo and as a pre-built docker image:

docker run harisekhon/pytools dockerhub_search.py harisekhon

There are lots of tagged versions of official software in my repos to allow development testing across multiple versions, usually more versions than available from the official repos (and new version updates available on request, just raise a GitHub issue).

DockerHub tags are not shown by docker search (docker issue 17238) so I wrote dockerhub_show_tags.py available in my DevOps Python Tools github repo and as a pre-built docker image - eg. to see an organized list of all CentOS tags:

docker run harisekhon/pytools dockerhub_show_tags.py centos

For service technologies like Hadoop, HBase, ZooKeeper etc for which you'll also want port mappings, each directory in the GitHub project contains both a standard docker-compose configuration as well as a make run shortcut (which doesn't require docker-compose to be installed) - either way you don't have to remember all the command line switches and port number specifics:

cd zookeeper
docker-compose up

or for technologies with interactive shells like Spark, ZooKeeper, HBase, Drill, Cassandra where you want to be dropped in to an interactive shell, use the make run shortcut instead:

cd zookeeper
make run

which is much easier to type and remember than the equivalent bigger commands like:

docker run -ti -p 2181:2181 harisekhon/zookeeper

and avoid this for more complex services like Hadoop / HBase:

docker run -ti -p 2181:2181 -p 8080:8080 -p 8085:8085 -p 9090:9090 -p 9095:9095 -p 16000:16000 -p 16010:16010 -p 16201:16201 -p 16301:16301 harisekhon/hbase

docker run -ti -p 8020:8020 -p 8032:8032 -p 8088:8088 -p 9000:9000 -p 10020:10020 -p 19888:19888 -p 50010:50010 -p 50020:50020 -p 50070:50070 -p 50075:50075 -p 50090:50090 harisekhon/hadoop

Github repos

DockerHub GitHub Ubuntu

My GitHub repo pre-built on major Linux distros with CLI programs located at /github/<project>

Available as both harisekhon/github:<distro> and harisekhon/<distro>-github for convenience, and to allow shorter use of :latest by using just harisekhon/github

harisekhon/github:latest is the same as harisekhon/github:ubuntu

Base Images

Linux Distros + Development Tools

Available as both harisekhon/<distro>-dev and harisekhon/dev:<distro>

harisekhon/dev:latest is the same as harisekhon/dev:ubuntu

Base Images of Java / Scala

All builds use OpenJDK with jre and jdk numbered tags. See this article below for why it might be illegal to bundle Oracle Java (and why no Linux distributions do this either):

Build from Source

All images come pre-built on DockerHub but if you want to compile from source for any reason such as developing improvements, I've made this easy to do:

git clone https://github.com/HariSekhon/Dockerfiles

cd Dockerfiles

To build all Docker images, just run the make command at the top level:

make

To build a specific Docker image, enter its directory and run make:

cd nagios-plugins

make

You can also build a specific version by checking out the git branch for the version and running the build:

cd consul
git checkout consul-0.9
make

or build all versions of a given software project like so:

cd hadoop
make build-versions

See the top level Makefile as well as the Makefile.in which is sourced per project with any project specific overrides in the <project_directory>/Makefile.
