Installing Gitlab

1.1. Obtain gitlab image package

docker pull gitlab/gitlab-ce      # Community Edition (CE) here represents community specimens,

1.2. Prepare gitlab working directory on the machine

mkdir -p /data/gitlab/config  # Create config directory
mkdir -p /data/gitlab/logs    # Create logs directory
mkdir -p /data/gitlab/data    # Create data directory

1.3 mirror and start

Since port 80 of the server may be occupied, we have changed it to another port to start

docker run --detach     --hostname :IP     --publish 7001:443 --publish 7002:80 --publish 7003:22     --name gitlab --restart always     --volume /data/gitlab/config:/etc/gitlab     --volume /data/gitlab/logs:/var/log/gitlab     --volume /data/gitlab/data:/var/opt/gitlab --volume /etc/localtime:/etc/localtime gitlab/gitlab-ce

docker run -d -p 2443:443 -p 5678:80 -p 2222:22 --name gitlab --restart always -v /srv/gitlab/config:/etc/gitlab -v /srv/gitlab/logs:/var/log/gitlab -v /src/gitlab/data:/var/opt/gitlab docker.io/gitlab/gitlab-ce

Parameter name	Parameter description
detach	Specifies whether the container runs in the foreground or background
hostname	Specify the host address. If there is a domain name, you can point to the domain name
publish	Specify the port exposed by the container. The port on the left represents the port of the host machine, and the port on the right represents the port of the container
name	Give the container a name
restart always	Always restart
volume	Data volume is the most important knowledge point in docker

Parameter description of the script, Please refer to the official documents for details

1.4. Modify configuration file

Modify gitlab YML file

vim /src/gitlab/data/gitlab-rails/etc/gitlab.yml
Find the following configuration, modify the IP or domain name that the host serves you (http: / /) and save and exit after modification

Modify gitlab RB file

external_url 'http://192.168.16.200:7002'
gitlab_rails['gitlab_ssh_host'] = '192.168.16.200'
gitlab_rails['gitlab_shell_ssh_port'] = 7003

1.5 restart gitlab

Stop and remove previously started gitlab
stop it
docker stop gitlab
remove
docker rm gitlab
Restart gitlab

1.6 and 4.8 check the local port status again

netstat -tnl # command

1.7. Open firewall port

[root@h200 ~]# firewall-cmd --zone=public --permanent --add-port=7002/tcp
success
[root@h200 ~]# firewall-cmd --zone=public --permanent --add-port=1001/tcp
success
[root@h200 ~]# firewall-cmd --zone=public --permanent --add-port=1003/tcp
success
[root@h200 ~]# 
[root@h200 ~]# firewall-cmd --reload
success
[root@h200 ~]#

Container internal commands

gitlab-ctl reconfigure　　// Reapply gitlab configuration
gitlab-ctl restart　　　　// Restart gitlab service
gitlab-ctl status　　　   // View gitlab running status
gitlab-ctl stop　　　　  // Stop gitlab service
gitlab-ctl tail　　　　　// View gitlab run log

Installing gitlab runner

You can configure settings -- > cicd -- > Runner in a project, or you can install shared Runner on the GitLab main settings page. The installation methods are the same

1. Pull the Runner image and start it

docker run -d --name gitlab-runner --restart always -v /srv/gitlab-runner/config:/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest  

2. Enter the Runner container

docker exec -it gitlab-runner bash

3. Run the following command

gitlab-runner register

Enter the address of the Gitlab instance

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com )
http://xxx

Enter a token

Please enter the gitlab-ci token for this runner
xxx

Enter a description of the Runner

Please enter the gitlab-ci description for this runner
[hostname] my-runner

Enter the label associated with the Runner

Please enter the gitlab-ci tags for this runner (comma separated):
my-tag,another-tag

Enter the performer of Ruuner

Please enter the executor: ssh, docker+machine, docker-ssh+machine, kubernetes, docker, parallels, virtualbox, docker-ssh, shell:
docker

If the above executor is docker, you need to gitlab-ci. Specify docker version in YML

Please enter the Docker image (eg. ruby:2.1):
alpine:latest

After passing the above command, you can view the newly created runner in gitlab

4. Modify Runner profile

vim /srv/gitlab-runner/config/config.toml

Find the volumes configuration and modify it as follows: mount the docker of the host and configure the cache of Maven to improve efficiency

volumes = ["/cache","/var/run/docker.sock:/var/run/docker.sock","/data/.m2/:/.m2/"]

Add a line of configuration below the volumes configuration to prevent the Runner from repeatedly pulling images

pull_policy = "if-not-present"

Just restart the Runner

docker restart gitlab-runner
