飞天班第47节：Docker精通-5

# 1、卸载旧的版本
yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

# 2、环境需求，软件包，仓库
yum install -y gcc
yum install -y gcc-c++

yum install -y yum-utils

# 3、配置镜像地址
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 4、更新软件索引包 
yum makecache fast

# 5、安装docker引擎
yum install -y docker-ce docker-ce-cli containerd.io

# 6、启动docker
systemctl enable docker
systemctl start docker

# 7、运行helloworld镜像测试
docker run hello-world

# 1、登录阿里云（容器镜像服务）
# 2、参考配置加速
sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://qiyb9988.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload

sudo systemctl restart docker

docker pull gitlab/gitlab-ce

# etc
mkdir -p /home/gitlab/etc
# data
mkdir -p /home/gitlab/data
# logs
mkdir -p /home/gitlab/logs

# 暴露https 443和http 80端口
# 挂载配置文件、数据、日志目录
docker run --name='gitlab' -d -p 4443:443 -p 8888:80 \
-v /home/gitlab/etc:/etc/gitlab \
-v /home/gitlab/data:/var/opt/gitlab \
-v /home/gitlab/logs:/var/log/gitlab \
gitlab/gitlab-ce:latest

# 第1次构建会比较慢，查看gitlab构建过程
docker logs -f gitlab

[root@helloworld ~]# docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS                    PORTS                                                 NAMES
993e11f205ad        gitlab/gitlab-ce:latest   "/assets/wrapper"        17 minutes ago      Up 17 minutes (healthy)   22/tcp, 0.0.0.0:8888->80/tcp, 0.0.0.0:4443->443/tcp   gitlab

[root@helloworld ~]#  cd /home/gitlab/etc
[root@helloworld etc]# vim gitlab.rb
external_url 'http://192.168.56.103'

# /home/gitlab/data/gitlab-rails/etc/gitlab.yml  
[root@helloworld data]# cd /home/gitlab/data
[root@helloworld data]# cd gitlab-rails/
[root@helloworld gitlab-rails]# cd etc/
[root@helloworld etc]# vim gitlab.yml 
看下面https:false,是使用80端口http协议，如果是true，就是使用443端口https协议，那么上面的gitlab.rb中的external_url
要修改为“ https://192.168.56.103 ”

[root@helloworld etc]# docker restart gitlab
# 启动过程中查看日志
[root@helloworld etc]# docker logs -f gitlab

systemctl restart docker

jenkins/jenkins     latest              6328c71fe374        2 days ago          659MB 

# 1、挂载目录和docker容器内同步！
mkdir -p /var/jenkins_home
chmod 777 /var/jenkins_home

# 2、run
docker run \
  -u root \
  -d \
  -p 8080:8080 \
  -p 50000:50000 \
  -v /var/jenkins_home:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  --name jenkins \
  jenkinsci/blueocean

# 查看容器的日志
docker logs -f jenkins

# 插件下载慢，配置updates加速地址
cd /var/jenkins_home/updates
# 执行脚本如下
#把 “ www.google.com ”  改成  “ http://www.baidu.com/ ”
#全局搜索 “ updates.jenkins-ci.org/download ” 替换成 mirrors.tuna.tsinghua.edu.cn/jenkins
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json

# 注意：不用重启jenkins

[root@helloworld updates]# docker rm -f -v  jenkins
# 删除挂载的目录
[root@helloworld var]# rm -rf jenkins_home/
