Docker-Compose部署GitLab

修改静态 IP 、DNS和主机名

修改 静态IP

编辑 vi /etc/netplan/50-cloud-init.yaml 配置文件，修改内容如下

network:
  version: 2
  ethernets:
    ens33:
      dhcp4: no
      dhcp6: no
      addresses: [192.168.137.254/24]
      gateway4: 192.168.137.1
      nameservers:
        addresses: [114.114.114.114, 8.8.8.8]

使用 netplan apply 命令让配置生效

修改DNS

1. # 取消 DNS 行注释，并增加 DNS 配置如：114.114.114.114，8.8.8.8修改后重启下计算机
2. vi /etc/systemd/resolved.conf

修改主机名

修改 cloud.cfg 防止重启后主机名还原

1. vi /etc/cloud/cloud.cfg
2. ``
3. # 该配置默认为 false，修改为 true 即可
4. preserve_hostname: true

修改主机名

1. # 修改主机名
2. hostnamectl set-hostname gitlab
3. ``
4. # 配置 hosts
5. vim /etc/hosts
6. 192.168.137.254 gitlab

安装Docker

卸载旧版本

apt-get remove docker docker-engine docker.io containerd runc

使用 APT 安装

# 更新数据源
apt-get update
# 安装所需依赖
apt-get -y install apt-transport-https ca-certificates curl software-properties-common
# 安装 GPG 证书
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
# 新增数据源
add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
# 更新并安装 Docker CE
apt-get update && apt-get install -y docker-ce

验证安装是否成功

docker version

1. vim /etc/docker/daemon.json

2. {

3. "registry-mirrors": ["https://xxxxxxxx.mirror.aliyuncs.com"]

4. }

5. # 重启 Docker

6. systemctl daemon-reload

7. systemctl restart docker

选择安装汉化版的twang2218/gitlab-ce-zh

docker pull twang2218/gitlab-ce-zh

创建docker-compose本机目录

mkdir -p /usr/local/docker/gitlab

cd /usr/local/docker/gitlab

touch docker-compose.yml

vi docker-compose.yml

在docker-compose.yml目录下构建并且启动docker容器

docker-compose up -d

常用docker-compose的命令

docker-compose stop 停止容器

docker-compose start 启动容器

docker-compose logs 查看容器日志

docker-compose logs -f 查看容器实时日志

docker-compose down 停止后删除容器
