docker

1.

Docker常用命令
docker基础

2.离线安装docker

离线安装docker

1. 下载地址：
   https://download.docker.com/linux/static/stable/x86_64/
   我下载的版本为：docker-19.03.9.tgz

2. 安装

1、解压
tar -xvf docker-19.03.9.tgz
2、将解压出来的docker文件内容移动到 /usr/bin/ 目录下
cp docker/* /usr/bin/
3、将docker注册为service
vim /etc/systemd/system/docker.service
4.将下列配置加到docker.service中并保存

[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
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
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=onfailure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target

3. 启动
   chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker
   systemctl daemon-reload #重载unit配置文件
   systemctl enable docker.service # 生成自启动服务
   systemctl start docker #启动Docker
   systemctl enable docker 　　　　　　　　 # 设置开机自启动服务

3. docker-compose安装

1. 下载地址
   https://github.com/docker/compose/releases

2. 安装

3. cd /usr/local/bin

4. mv docker-compose-Linux-x86_64 docker-compose

5. sudo chmod +x docker-compose

6. docker-compose启动报错，没有权限
   把“/etc/selinux/config”里面的SELINUX值修改为disabled
   SELINUX=disabled
   重启服务器

4. docker image

docker inspect [cid]

5. 事先

chmod 777 -R /data/docker_file/grafana
chmod 777 -R /data/docker_file/promethus
chmod 777 -R /data/docker_file/monitor

docker save -o nginx.tar nginx:latest
docker load -i nginx.tar

6.promethus告警

1.Prometheus 监控报警系统 AlertManager 之邮件告警

2.Spring Boot 微服务应用集成Prometheus + Grafana 实现监控告警

3.Alertmanager报警

4.官方文档

5.prometheus + consul
6.不错的博客

7. prometheus热更新

docker run --name prometheus -d -p 9090:9090 --restart=always -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml -v /opt/prometheus/rules.yml:/opt/prometheus/rules.yml prom/prometheus --config.file=/etc/prometheus/prometheus.yml --web.enable-lifecycle

curl -X POST http://localhost:9090/-/reload
