Update: Docker Image

Update Official Backdrop CMS Docker Image

Two Steps (details for each step below)

1. Update the Backdrop Docker repository
2. Create a PR to update the Docker repository

1. Update the backdrop-ops/docker image https://github.com/backdrop-ops/backdrop-docker

• File an issue

You will need 2 things:

1. The release tag of the latest stable Backdrop version (which is usually the same as the Backdrop version).
2. The md5 hash of the latest stable Backdrop release:
   • 2.1 Download the "Source code" .tar.gz file - NOT the .zip file (it is usually the last item in the list of links bellow the "Assets" section).
   • 2.1 Run md5 {filename}.tar.gz or md5sum {filename}.tar.gz depending on your operating system
   • 2.2 Make a note of the generated md5 hash

• Update the 2 dockerfiles:
  • Update 1/apache/Dockerfile:
    • Update ENV BACKDROP_VERSION to the new release tag (point 1 above)
    • Update ENV BACKDROP_MD5 to the new md5 hash (point 2.2 above)
  • Update 1/fpm/Dockerfile:
    • Update ENV BACKDROP_VERSION to the new release tag (point 1 above)
    • Update ENV BACKDROP_MD5 to the new md5 hash (point 2.2 above)
• Create a Pull Request against https://github.com/backdrop-ops/backdrop-docker
  • If Travis tests pass -- Merge the PR
  • Make a note of the merge commit hash, as you will need it for updating the official docker-library (see next section)

Update the README in https://github.com/backdrop-ops/backdrop-docker

• Edit https://github.com/backdrop-ops/backdrop-docker/blob/master/README.md
  • Update the version numbers in the "Supported tags and respective Dockerfile links" section at the top
  • more???

2. Tell the Docker official images to build against the latest source

• A PR needs to be submitted against the official docker-images repo

• Update the 2 lines starting with Tags:, so to reflect the latest version of Backdrop. For example, change from this:

  Tags: 1.13.1, 1.13, 1, 1.13.1-apache, 1.13-apache, 1-apache, apache, latest

  ...to this:

  Tags: 1.13.2, 1.13, 1, 1.13.2-apache, 1.13-apache, 1-apache, apache, latest

• Update the git commit:

  • Make sure that the PR you have filed in the previous section has been committed -> Head to the commits list of the https://github.com/backdrop-ops/backdrop-docker repo. -> Click on the latest commit which updated the dockerfiles -> the full commit hash should be located at the top-right of the page, below the "Browse files" button.
  • Use the commit hash from the previous step, to update the 2 lines starting with GitCommit:

In order to help the Docker Library maintainers review and merge the PR, make sure to add as much useful info in the PR summary, such as:

• a link to the latest release of Backdrop
• a link to the latest commit in https://github.com/backdrop-ops/backdrop-docker/commits/master
