Gitlab搭建

前置条件

已安装docker和docker compose

配置docker-compose

#1.创建目录 
/opt/docker/gitlab

#2.创建配置文件
vim docker-compose.yml

内容为：

version: '3'
services:
    gitlab:
      image: 'gitlab/gitlab-ce'
      restart: unless-stopped
      hostname: '172.xx.xxx.x'
      container_name: gitlab
      environment:
        TZ: 'Asia/Shanghai'
        GITLAB_OMNIBUS_CONFIG:
          external_url 'http://172.xx.xxx.x:9980'
          gitlab_rails['time_zone'] = 'Asia/Shanghai'
          # 需要配置到 gitlab.rb 中的配置可以在这里配置，每个配置一行，注意缩进。
          # ssh主机ip
           gitlab_rails['gitlab_ssh_host'] = '172.xx.xxx.x'
          #ssh连接端口
           gitlab_rails['gitlab_shell_ssh_port'] = 9922
      ports:
        - '9980:9980'
        - '443:443'
        - '9922:22'
      volumes:
        - /home/gitlab/config:/etc/gitlab
        - /home/gitlab/data:/var/opt/gitlab
        - /home/gitlab/logs:/var/log/gitlab

#3.运行
docker-compose up -d

#4.进入容器查看初始密码
docker exec -it gitlab /bin/bash
cat /etc/gitlab/initial_root_password 

#5.登陆
http://172.xx.xxx.x:9980
账号：root
密码：初始密码

Docker

1.卸载旧版本
 yum remove docker \
                   docker-client \
                   docker-client-latest \
                   docker-common \
                   docker-latest \
                   docker-latest-logrotate \
                   docker-logrotate \
                   docker-selinux \
                   docker-engine-selinux \
                   docker-engine \
                   docker-ce
                   
2.安装yum工具
 yum install -y yum-utils \
            device-mapper-persistent-data \
            lvm2 --skip-broken
            
3.更新本地镜像源
#3.1
yum-config-manager \
     --add-repo \
     https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#3.2 
sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo

#.33
yum makecache fast

4.安装docker
yum install -y docker-ce

5.关闭防火墙
所有节点
#查看状态
systemctl status firewalld.service
#停止
systemctl stop firewalld.service
#禁用
systemctl disable firewalld.service

6.启动docker
systemctl start docker  # 启动docker服务
ps：
systemctl stop docker  # 停止docker服务
systemctl restart docker  # 重启docker服务

7.配置镜像加速
自己注册阿里云账号，阿里云会分配一个加速器地址，在容器镜像服务控制台-镜像加速器中
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://xxxxeq2g.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

8.安装docker-compose
 # 安装
 curl -L https://github.com/docker/compose/releases/download/1.23.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
 
 如果下载速度较慢，或者下载失败，可以先自行在网上下载好docker-compose文件，然后上传到/usr/local/bin/目录也可以。
 
9.修改docker-compose文件权限
chmod +x /usr/local/bin/docker-compose

Portainer

docker可视化工具

$ docker volume create portainer_data
$ docker run -d -p 9090:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

http://172.xx.xxx.x:9090
