Developing Dockerfiles and infrastructure

Developing Dockerfiles

To develop Dockerfiles, you can use a server that's not serving any live domains, use docker locally on your laptop, or use the vagrant up instructions to run the infrastructure inside vagrant.

Developing infrastructure

To develop the infrastructure, create a branch on the infrastructure repo and specify that branch at the end of the deploy command, for instance:

sh ./deploy/deploy.sh k4 dev

Will deploy a server at whatever IP address "k4" points to in your /etc/hosts, using the "dev" branch of https://github.com/indiehosters/infrastructure.

Testing new Dockerfiles in the infrastructure

To test the infrastructure with a changed Dockerfile, you need to take several steps:

  • Develop the new Dockerfiles as described above at "Developing Dockerfiles"
  • When you're happy with the result, publish this new Dockerfile onto the docker hub registry under your own username (e.g. michielbdejong/haproxy-with-http-2.0)
  • Now create a branch on the infrastructure repo (e.g. "dev-http-2.0")
  • In this branch, grep for the Dockerfile you are updating, and replace its name with the experimental one everywhere:
    • the docker pull statement in scripts/setup.sh
    • the docker run statement in the appropriate systemd service file inside unit-files/
  • Push the branch to the https://github.com/indiehosters/infrastructure repo
  • Now deploy a server from your experimental infrastructure branch (which references your experimental Docker image), as described above at "Developing infrastructure"
