docker 常用操作命令整理

镜像仓库

将 docker 镜像仓库更换为阿里云镜像，Ubuntu、CentOS 可以按照如下命令操作。更多操作系统支持参考阿里云文档

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'

  "registry-mirrors": ["https://tatggrb0.mirror.aliyuncs.com"]

EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

镜像

1、拉取 docker 镜像

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker pull ubuntu:18.04
18.04: Pulling from library/ubuntu
7ddbc47eeb70: Pull complete 
c1bbdc448b72: Pull complete 
8c3b70e39044: Pull complete

Status: Downloaded newer image for ubuntu:18.04
docker.io/library/ubuntu:18.04

2、查看 docker 镜像

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker images

3、删除镜像

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker rmi d5e7f166b406

5、构建镜像
在Dockerfile文件的所在路径执行如下命令，-t 指定镜像名称，末尾的点标识 Dockerfile 文件的路径。

docker build -t imageName:tag .

容器

1、运行容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker run -it ubuntu:19.10
root@fad4c851e732:/# 

2、查看运行的容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
fad4c851e732        ubuntu:19.10        "/bin/bash"         About an hour ago   Up About an hour                        wonderful_roentgen

3、查看所有的容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
fad4c851e732        ubuntu:19.10        "/bin/bash"         About an hour ago   Exited (0) 5 seconds ago                       wonderful_roentgen
2b18b881a53c        hello-world         "/hello"            32 hours ago        Exited (0) 32 hours ago                        laughing_margulis

4、重新进入容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker attach fad4c851e732
root@fad4c851e732:/home/software/apache/hadoop# 

5、将一个已经终止的容器运行起来

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker start fad4c851e732
fad4c851e732
[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# 

6、终止容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker ps -a                            
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS                    PORTS               NAMES
3b395bf32944        ubuntu:hadoop       "/bin/bash"         About a minute ago   Up About a minute                             goofy_brahmagupta
fad4c851e732        ubuntu:19.10        "/bin/bash"         2 hours ago          Up 12 minutes                                 wonderful_roentgen
2b18b881a53c        hello-world         "/hello"            33 hours ago         Exited (0) 33 hours ago                       laughing_margulis
root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker stop 3b395bf32944
3b395bf32944

7、删除容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker ps -a                            
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS                    PORTS               NAMES
3b395bf32944        ubuntu:hadoop       "/bin/bash"         About a minute ago   Up About a minute                             goofy_brahmagupta
fad4c851e732        ubuntu:19.10        "/bin/bash"         2 hours ago          Up 12 minutes                                 wonderful_roentgen
2b18b881a53c        hello-world         "/hello"            33 hours ago         Exited (0) 33 hours ago                       laughing_margulis
[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker rm 3b395bf32944  
3b395bf32944
[root@iZ2ze6ogddtzz4dzyy00xwZ ~]#

8、创建容器时设置名称

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker run -d --name hadoop_master ubuntu:hadoop

9、重命名容器

[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
9d52a5a8f11e        ubuntu:hadoop       "/bin/bash"         3 minutes ago       Up 3 minutes                            ecstatic_archimedes
abbd553e65ae        ubuntu:hadoop       "/bin/bash"         4 minutes ago       Up 4 minutes                            peaceful_gould
bdb5742bba1c        ubuntu:hadoop       "/bin/bash"         8 minutes ago       Up 8 minutes                            hadoop_master
[root@iZ2ze6ogddtzz4dzyy00xwZ ~]# docker rename peaceful_gould hadoop_slave1

10、重新进入容器2

docker exec -it container-name /bin/bash

11、删除正在运行的容器

docker rm -f container-name
