docker 查看当前所有的容器

docker ps -a

  1. [root@izr86 ~]# docker ps -a
  2. CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS               NAMES
  3. 1ccd3d443198        hello-world         "/hello"            43 hours ago        Exited (0) 43 hours ago                       elated_lamarr
  4. 256192dc46e4        hello-world         "/hello"            2 days ago          Exited (0) 2 days ago                         great_gould
  5. [root@izr86 ~]#

docker 查看最新创建的容器

docker ps -l

  1. [root@izr86 ~]# docker ps -l
  2. CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS               NAMES
  3. 1ccd3d443198        hello-world         "/hello"            43 hours ago        Exited (0) 43 hours ago                       elated_lamarr
  4. [root@izr86 ~]#

创建容器：

docker create nginx(容器的名称)

此时创建的容器是停止状态的，没有运行的

  1. [root@izr86 ~]# docker create nginx
  2. Unable to find image 'nginx:latest' locally
  3. latest: Pulling from library/nginx
  4. 8d691f585fa8: Pull complete 
  5. 5b07f4e08ad0: Pull complete 
  6. abc291867bca: Pull complete 
  7. Digest: sha256:922c815aa4df050d4df476e92daed4231f466acc8ee90e0e774951b0fd7195a4
  8. Status: Downloaded newer image for nginx:latest
  9. 154847240dc658655e9d5bb496eeca837fe0e9a5d4561c16833bfcb6b4f71673
  10. [root@izr86 ~]# docker ps -a
  11. CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                    PORTS               NAMES

  14. 256192dc46e4        hello-world         "/hello"                 2 days ago          Exited (0) 2 days ago                         great_gould
  15. [root@izr86 ~]#

删除容器

容器删除之前，要停止运行

首先要查看要删除的容器是否在运行

docker ps 查看当前运行的容器

  1. [root@izr86 ~]# docker ps
  2. CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

查看了当前的容器之后，我们删除一个容器

  1. 256192dc46e4        hello-world         "/hello"                 2 days ago          Exited (0) 2 days ago                         great_gould
  2. [root@izr86 ~]# docker rm 256192dc46e4
  3. 256192dc46e4

可以根据容器的id删除一个容器，或者是根据名称删除一个id

docker 启动容器

docker start 容器名称/id

  1. [root@izr86 ~]# docker ps -l
  2. CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                          PORTS               NAMES
  3. 39ab25ad95fa        nginx               "nginx -g 'daemon of…"   15 minutes ago      Exited (0) About a minute ago                       nginx1
  4. [root@izr86 ~]# docker start nginx1
  5. nginx1

docker 关闭运行的容器

docker stop 容器名称/id

  1. [root@izr86 ~]# docker ps
  2. CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                          NAMES
  3. 39ab25ad95fa        nginx               "nginx -g 'daemon of…"   10 minutes ago      Up 10 minutes       80/tcp, 0.0.0.0:8090->90/tcp   nginx1
  4. [root@izr86 ~]# docker stop 39ab25ad95fa
  5. 39ab25ad95fa

docker 运行一个容器

docker run -d -p 8090:90

-d 表示容器在后台运行，-p 表示将容器的 80 端口映射到宿主机的 8080 端口，

  1. [root@izr86 ~]# docker run -d -p 8090:90 nginx
  2. cf781e80699b3d3c044a469ef0db63e971eb2cc84bcc1a94004e98e61166eb77

  18. [root@izr86 ~]#

但是我们现在是无法外网8090的，或者说访问不通

因为我们绑定的是docker的90端口，我们必须绑定docker的80端口才能进行通过外网访问

  1. [root@izr86o15kikb3az ~]# docker run -d -p 8090:80 nginx
