gitlab-images v0.3.0

gitlab-images

gitlab-images is in alpha. Expect breaking changes, crashes and big explosions. Use under your responsability 😇

CLI tool to convert a gitlab repository to a managed gitlab docker image registry

Tested only with a custom gitlab instance, don't know if it works with gitlab.org

Installation

To install it, you will need to have already configured:

• Your own gitlab instance
• With the container registry enabled
• A gitlab runner that can build docker images
  • If you wish, you can check my notes for docker image building inside a runner at docs.foxdev.io/docker-image-building

When you have your gitlab + runner + container registry, you can continue

• Install the tool npm i -g gitlab-images
• Create a new repository in your gitlab instance
  • For the examples I will use a repository at gitlab.mydomain.com/devops/images and a docker registry at registry.mydomain.com
• git clone ssh://git@gitlab.mydomain.com/devops/images.git
• cd images
• gitlab-images install
  • The installation wizard should be self explanatory, just fill the questions
  • To see an example of the command, go to "gitlab-images install example output" section
  • IMPORTANT follow the message at the end of the installation!
• Now you have your gitlab-images repo installed

When you push the changes, your runner should start a pipeline with 2 jobs: - 🛠️ docker-builder - 🏷️ docker-builder CI_SHA > production

Jobs with the emoji 🛠️ are builds, and with 🏷️ tagging jobs.

At this point, your repository is initialized with gitlab-images

fox@foxdev:~/git/devops/lab$ gitlab-images install
Debugger attached.
gitlab-images v0.2.0
Wellcome to the installation wizard🧙 for gitlab-images

Target path '/home/fox/git/devops/lab'

? Is this the path where you want to install gitlab-images? Yes

No 'gitlab-images.config.yml' found. Assuming new installation

? Your gitlab registry (ex: registry.your-gitlab.com) registry.mydomain.com
? Where will be the images located? (ex: /devops/images) /devops/images

This configuration will be used to execute command
? Is 'registry.mydomain.com/devops/images' correct? Yes

-=Docker builder image=-

The docker builder meta image is the image that will be used to build your images
You can modify whatever you want in it, add debugging tooling for your docker images etc

? Coma separated list of tags for the runners that will build images exec:docker,service:docker-builder

  - exec:docker
  - service:docker-builder

? Are this tags correct? Yes
No README.md found. A new one will be created

-=Installation=-
We are going to make modifications inside the path

/home/fox/git/devops/lab

Its recommended first to have a repository initialized, so you can diff the changes, or revert if the tool brokes something

? Install? Yes
EXEC> mkdir .devops
EXEC> cp $TEMPLATES/install/.devops/gitlab-images.hbs.yml > ~Hydrate~ > .devops/gitlab-images.yml
EXEC> cp $TEMPLATES/install/.gitignore > .gitignore
EXEC> mkdir docker-builder
EXEC> cp $TEMPLATES/install/docker-builder/.config.yml > docker-builder/.config.yml
EXEC> cp $TEMPLATES/install/docker-builder/Dockerfile > docker-builder/Dockerfile
EXEC> cp $TEMPLATES/install/docker-builder/gitlab-images-0.2.0.tgz > docker-builder/gitlab-images-0.2.0.tgz
EXEC> cp $TEMPLATES/install/gitlab-images.config.hbs.yml > ~Hydrate~ > gitlab-images.config.yml
EXEC> cp $TEMPLATES/install/README.hbs.md > ~Hydrate~ > README.md

-=gitlab-images installed!=-
If is the first time installing gitlab-images (aka is not an update) follow this!
Before pushing the changes, the first docker-builder image must be manually created

Please run:
$  docker login registry.mydomain.com
$  gitlab-images docker build docker-builder
   - Select "production" tag
   - Push to registry: yes

To initialize the first docker-builder image

When you are done, you can commit and push the changes:
$  git add --all
$  git commit -m "Initialized gitlab-images"
$  git push

Installation done! 🚀
