# Docker

## Docker常用命令

`docker pull image_name`：下载镜像 `docker ps`：列出正在运行中的容器 `docker ps ‑a`：列出所有容器（包括未运行的） `docker stop container_id`：停止运行容器 `docker start container_id`：启动容器 `docker restart container_id`：重启容器 `docker rm container_id`：删除容器 `docker rm ‑f container_id`：删除正在运行中容器 `docker rmi image_id`：删除镜像

## Docker镜像和容器概念

`image（镜像）`文件可以看作是容器的模板。Docker 根据 image 文件生成容器的实例。`容器`简单来说容器为镜像的运行实例，Docker 容器是对 Linux容器（LXC）的封装

## Docker安装基础服务

### Redis

`docker pull redis` `docker run --name some-redis -d redis` `docker exec -ti {container_id} redis-cli`

### Zookeeper

`docker pull zookeeper` `docker run -p 2181:2181 --name some-zookeeper --restart always -d zookeeper` `docker run -it --rm --link some-zookeeper:zookeeper zookeeper zkCli.sh -server zookeeper`

### MariaDB

`docker run -p 127.0.0.1:3306:3306 --name {container_name} -e MARIADB_ROOT_PASSWORD={password} -d mariadb:{tag}` `docker exec -it {container_name} bash` `mysql -h localhost -u root -p`

### Prometheus

`docker run --name prometheus -d -p 127.0.0.1:9090:9090 -v {path-to-prometheus.yml}:/etc/prometheus/prometheus.yml prom/prometheus`

node\_exporter `sudo docker run --name node_exporter --network="host" --pid="host" -v "/:/host:ro" prom/node-exporter:v1.0.0 --path.rootfs="/host"` (不支持 macos)

Grafana `docker run --name grafana -d -p 3000:3000 grafana/grafana` <https://grafana.com/grafana/dashboards/8919>

### RabbitMQ

`docker run -d --hostname rabbit-host1 --name rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=123456 -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management`
