🍀 Proposal: New Plugin Development: GitLab CE

[daniel-hutao]

What would you like to add? Why is this needed?

• To support local deployment of gitlab-ce
• Helm chart is preferred
• Please give a simple design before you start coding

Looks like a great idea, I'd like to work for it.

/assign @iyear Happy coding!

summary

I've spent most of the day researching how to deploy gitlab-ce, and have found some rather tricky issues.

1. gitlab-ce doesn't have an arm64 version or a darwin version of the image, so we can't run it locally. It only has the linux/amd64 version.

Related issues: Release arm64 docker images

2. If we use linux to test it, resource requirements:

I have done some tests and have some suggestions for you @iyear:

1. Deploy method: For simplicity, we start with docker support for the first version. Refer to the documentation here.
2. Docker container image: use docker pull gitlab/gitlab-ce:rc
3. OS support: linux only(we need to remind users in the documentation that the current plugin only supports linux deployment)
4. domain: We give a default value, such as gitlab.change.me, and preserve the ability for user-defined domain names in the configuration file. e.g. hostname=gitlab.devstream.io or domain=gitlab.devstream.io
5. https support: By default, this deploy method does not support https, but it doesn't matter, we can leave it to the next separate proposal to avoid making the first version too complicated. For more information on how to enable https, you can see here
6. plugin name: Considering that the deployment of gitlab is likely that we will have support for vm and helm in the future, I suggest that the current plugin be named gitlab-ce-docker

/cc @IronCore864 @aFlyBird0 Looking forward to your suggestions.

I have done some tests and have some suggestions for you @iyear:

1. `Deploy method`: For simplicity, we start with `docker` support for the first version. Refer to the [documentation here](https://docs.gitlab.com/ee/install/docker.html#install-gitlab-using-docker-engine).

2. `Docker container image`: use `docker pull gitlab/gitlab-ce:rc`

3. `OS support`: linux only(we need to remind users in the documentation that the current plugin only supports linux deployment)

4. `domain`: We give a default value, such as `gitlab.change.me`, and preserve the ability for user-defined domain names in the configuration file. e.g. `hostname=gitlab.devstream.io or domain=gitlab.devstream.io`

5. `https support`: By default, this deploy method does not support `https`, but it doesn't matter, we can leave it to the next separate proposal to avoid making the first version too complicated. For more information on how to enable https, you can see [here](https://docs.gitlab.com/omnibus/settings/nginx.html#enable-https)

6. `plugin name`: Considering that the deployment of gitlab is likely that we will have support for `vm` and `helm` in the future, I suggest that the current plugin be named `gitlab-ce-docker`

Great. Let's get started.
