Docker 安装

下载

下载docker二级制文件docker-20.10.9.tgz

https://download.docker.com/linux/static/stable/x86_64/docker-20.10.9.tgz

上传到/data目录

解压文件

cd /data

tar -zxf docker-20.10.9.tgz

移动解压出来的文件到/usr/bin目录

mv docker/* /usr/bin/

创建docker服务

cat > /etc/systemd/system/docker.service <<EOF

Unit

Description=Docker Application Container Engine

Documentation=https://docs.docker.com

After=network-online.target firewalld.service

Wants=network-online.target

Service

Type=notify

the default is not to use systemd for cgroups because the delegate issues still

exists and systemd currently does not support the cgroup feature set required

for containers run by docker

ExecStart=/usr/bin/dockerd --graph /data/docker -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

ExecReload=/bin/kill -s HUP $MAINPID

Having non-zero Limit*s causes performance problems due to accounting overhead

LimitNOFILE=infinity

LimitNPROC=infinity

LimitCORE=infinity

Uncomment TasksMax if your systemd version supports it.

Only systemd 226 and above support this version.

#TasksMax=infinity

TimeoutStartSec=0

set delegate yes so that systemd does not reset the cgroups of docker containers

Delegate=yes

kill only the docker process, not all processes in the cgroup

KillMode=process

restart the docker process if it exits prematurely

Restart=on-failure

StartLimitBurst=3

StartLimitInterval=60s

Install

WantedBy=multi-user.target

EOF

设置执行权限并启动docker服务

chmod +x /etc/systemd/system/docker.service

启动服务，并设置开机启动

systemctl daemon-reload && systemctl start docker && systemctl enable docker.service

验证服务器启动

systemctl status docker

安装docker-compose

上传docker-compose-linux-x86_64

配置执行权限

chmod +x docker-compose-linux-x86_64

重命名为docker-compose并移动到/usr/local/bin/目录

mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

验证

docker-compose -v

部署Gitlab

上传镜像

进入镜像目录，加载docker镜像

cd /data/gitlab/docker-compose/

docker load -I gitlab16.2.0.tar

修改配置文件

使用docker-compose通过yml配置文件启动容器

gitlab.yml文件内容

version: '3.8'

services:

web:

image: 'gitlab/gitlab-ce:16.2.0-ce.0' # 使用GitLab社区版镜像，也可使用gitlab/gitlab-ee:latest（企业版）

restart: always

user: 'root' # 设置容器中运行的用户为root用户

#hostname: 'gitlab' # 替换成你的GitLab主机名

container_name: 'gitlab'

environment:

GITLAB_OMNIBUS_CONFIG: |

external_url 'http://192.168.200.160' # 替换成你的GitLab访问URL

ports:

'80:80'
'443:443'
'2222:22' # 用于SSH访问

volumes:

'/data/gitlab/gitlab_home/config:/etc/gitlab'
'/data/gitlab/gitlab_home/logs:/var/log/gitlab'
'/data/gitlab/gitlab_home/data:/var/opt/gitlab'

privileged: true

启动容器

docker-compose -f gitlab.yml up -d

获取初始密码登录

等待Web界面启动

获取初始化密码

cat /data/gitlab/gitlab_home/config/initial_root_password
