Pre-requirement I installed Docker because I wanted to use Docker executor for better isolation of environments.
Install GitLab Runner on the server Follow the official manual.
https://docs.gitlab.com/runner/install/linux-repository.html
On Ubuntu From repo (recommended) curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash export GITLAB_RUNNER_DISABLE_SKEL=true; sudo -E apt install gitlab-runner Check.
$ sudo gitlab-runner status Runtime platform arch=amd64 os=linux pid=3163 revision=2ebc4dc4 version=13.9.0 gitlab-runner: Service is running! $ sudo gitlab-runner list Runtime platform arch=amd64 os=linux pid=3172 revision=2ebc4dc4 version=13.
Motivation I want to mirror GitLab repository to a bare Git repository which was hosted by Gitosis. As of Dec. 2020, GitLab Community Edition support “Push” only. “Push” means “mirror a GitLab (CE) repository to other Git repositories.”
How to set up - GitLab Allow GitLab to access outbound Otherwise, you got an error Remote mirrors url is blocked: Requests to the local network are not allowed. “Admin” -> “Settings” -> “Network” -> “Outbound Requests” -> “Allow requests to the local network from hooks and services”
Definitions of CI/CD (rough) https://docs.gitlab.com/ee/ci/introduction/
CI (Continuous Integration): Building and testing codes are automated. CD Continuous Delivery: One-click deploy enabled. Continuous Deployment: Auto deploy enabled. Facts about GitLab implementation GitLab Runner is an environment in which the CI/CD scripts run. We write the procedures in the file .gitlab-ci.yml normally. You need a GitLab Runner first.
Install and configure a Runner Please refer my GitLab Runner install post :)
How to write .
Install GitLab running on Docker Here is the official document. I followed it.
Caution: I’m using my GitLab on VM, not Docker image. Because the official image doesn’t contain e-mail client, and it is a little bit hard to understand. For me, deploying it on premise or VM is easy.
Install docker apt install -y docker.io Set path export GITLAB_HOME=/srv/gitlab Configurations and repositories would be stored in this path.
Run a container sudo docker run --detach \ --hostname {{ your_hostname }} \ --publish 443:443 --publish 80:80 --publish 2222:22 \ --name gitlab \ --restart always \ --volume $GITLAB_HOME/config:/etc/gitlab \ --volume $GITLAB_HOME/logs:/var/log/gitlab \ --volume $GITLAB_HOME/data:/var/opt/gitlab \ gitlab/gitlab-ce:latest I changed git port to 2222 because the server should be access by ssh.
Install GitLab with apt (official way as of 2020/08/11) sudo apt update sudo apt upgrade -y sudo apt-get install -y curl openssh-server ca-certificates tzdata sudo apt install -y postfix curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash sudo EXTERNAL_URL="https://{{ your_GitLab_server_domain }}" apt install gitlab-ce ## If you are using internal purpose and use your own domain, auto SSL configuration (ACME) would fail. ## Then, try http (not https) like below. ## sudo EXTERNAL_URL="http://{{ your_GitLab_server_domain }}" apt install gitlab-ce Configure TLS Create TLS self-sign CA certificate.
