容器container作為Docker三大基本概念之一，相當於一個系統中執行的軟體。一個映象下可以啟動多個容器。通過Docker命令可以檢視容器container支援的命令。
docker container --help
| 命令 | 等價命令 | 說明 |
|---|---|---|
| container attach | attach | 將本地標準輸入、輸出和錯誤流連線到執行中的容器 |
| container commit | commit | 根據當前容器建立一個新的映象 |
| container cp | cp | 將宿主機與容器之間複製檔案/資料夾 |
| container create | create | 建立一個新的容器 |
| container diff | diff | 檢查容器檔案系統上檔案或目錄的更改 |
| container exec | exec | 進入一個正在執行的容器 |
| container export | export | 將容器匯出為本地檔案 |
| container inspect | 檢視一個或多個容器詳細資訊 | |

接下來就詳細檢視每個命令的使用方式。
attach
將本地標準輸入、輸出和錯誤流連線到執行中的容器
docker container attach [OPTIONS] CONTAINER
or
docker attach [OPTIONS] CONTAINER
Options:
--detach-keys string Override the key sequence for detaching a container
--no-stdin Do not attach STDIN
--sig-proxy Proxy all received signals to the process (default true)
使用這個命令需要注意的時，當退出容器時，容器也會跟著停止。為了退出時容器不停止，可以使用引數--no-stdin。
commit
根據當前容器建立一個新的映象
docker container commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
or
docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
Options:
-a, --author string Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
-c, --change list Apply Dockerfile instruction to the created image
-m, --message string Commit message
-p, --pause Pause container during commit (default true)
這裡啟動的是一個tomcat容器
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ec4b4f0fd45c 4b "catalina.sh run" 18 minutes ago Up 18 minutes 0.0.0.0:8088->8080/tcp, :::8088->8080/tcp fervent_goldberg
將這個容器製作一個新的容器
docker commit -a "arvin88" -m "測試commit命令" ec4b4f0fd45c arvin88/tomcat_user:v1
sha256:77fc61f55a0ca2b504db9265c950168bca7045a7a925abf649c1abaa9a311566
檢視映象
REPOSITORY TAG IMAGE ID CREATED SIZE
arvin88/tomcat_user v1 77fc61f55a0c 32 seconds ago 590MB
可以看到已經建立成功
注意：如果不指定倉庫源：版本，預設建立出來的就是
，可以通過tag命令來重新指定倉庫源：版本
cp
將宿主機與容器之間複製檔案/資料夾
docker container cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH
or
docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PAT
Options:
-a, --archive Archive mode (copy all uid/gid information)
-L, --follow-link Always follow symbol link in SRC_PATH
將宿主機的test.py檔案拷貝到tomcat容器的webapps目錄下
docker cp test.py ec4b4f0fd45c:/usr/local/tomcat/webapps
create
建立一個新的容器
docker container create [OPTIONS] IMAGE [COMMAND] [ARG...]
or
docker create [OPTIONS] IMAGE [COMMAND] [ARG...]
引數有點多，這裡就不列出來了，有興趣可以使用--help檢視。
docker create -it -p 8089:8080 77fc61f55a0c
建立的新容器，預設是未啟動的，可以使用start命令啟動。
docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e5e2f9915c42 77fc61f55a0c "catalina.sh run" 7 seconds ago Created frosty_ellis
ec4b4f0fd45c 4b "catalina.sh run" 37 minutes ago Up 37 minutes 0.0.0.0:8088->8080/tcp, :::8088->8080/tcp fervent_goldberg
docker start ec
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e5e2f9915c42 77fc61f55a0c "catalina.sh run" 42 seconds ago Up 2 seconds 0.0.0.0:8089->8080/tcp, :::8089->8080/tcp frosty_ellis
ec4b4f0fd45c 4b "catalina.sh run" 38 minutes ago Up 38 minutes 0.0.0.0:8088->8080/tcp, :::8088->8080/tcp fervent_goldberg
diff
檢查容器檔案系統上檔案或目錄的更改
docker container diff CONTAINER
docker diff CONTAINER
這個命令比較簡單，沒有其他引數。
docker diff e5e2f9915c42
C /usr
C /usr/local
C /usr/local/tomcat
C /usr/local/tomcat/logs
C /usr/local/tomcat/logs/catalina.2021-08-01.log
C /usr/local/tomcat/logs/localhost.2021-08-01.log
C /tmp
C /tmp/hsperfdata_root
C /tmp/hsperfdata_root/1
exec
進入一個正在執行的容器
docker container exec [OPTIONS] CONTAINER COMMAND [ARG...]
or
docker exec [OPTIONS] CONTAINER COMMAND [ARG...]
Options:
-d, --detach Detached mode: run command in the background
--detach-keys string Override the key sequence for detaching a container
-e, --env list Set environment variables
--env-file list Read in a file of environment variables
-i, --interactive Keep STDIN open even if not attached
--privileged Give extended privileges to the command
-t, --tty Allocate a pseudo-TTY
-u, --user string Username or UID (format: <name|uid>[:<group|gid>])
-w, --workdir string Working directory inside the container
通常使用-i -t引數，進入容器
docker exec -it e5 /bin/bas
root@e5e2f9915c42:/usr/local/tomcat# ls
看到root後面跟著容器ID，則表示進入到容器了，如果想退出容器，使用exit命令，就可以退出容器。
export
將容器匯出為本地檔案
docker container export [OPTIONS] CONTAINER
or
docker export [OPTIONS] CONTAINER
Options:
-o, --output string Write to a file, instead of STDOUT
這個必須要帶引數
docker export -o "tomcat_user_v1.gz.tar" e5
輸出的檔案路徑支援絕對路徑，如果不填絕對路徑，則預設就是在當前執行匯出命令的目錄下，使用ll或ls檢視檔案。
-rw-------. 1 root root 588863488 Aug 1 11:51 tomcat_user_v1.gz.tar
從結果上看出已經匯出成功。
inspect
檢視一個或多個容器詳細資訊
docker container inspect [OPTIONS] CONTAINER [CONTAINER...]
Options:
-f, --format string Format the output using the given Go template
-s, --size Display total file sizes
命令：docker container inspect e5e2f9915c42，輸出的內容太多了，就不貼出來了，可以自行驗證檢視。

logs
獲取容器日誌
docker container logs [OPTIONS] CONTAINER
or
docker logs [OPTIONS] CONTAINER
Options:
--details Show extra details provided to logs

-q, --quiet Only display container IDs
-s, --size Display total file sizes
不加任何引數情況下，列出正在執行的容器：
docker container ls
or
docker ps
兩種命令效果一樣

從結果的STATUS列可以看到，後面多了(Paused)，表示容器已經暫停。
unpause
取消一個或多個暫停的容器
docker container unpause CONTAINER [CONTAINER...]
or
docker unpause CONTAINER [CONTAINER...]
上面我們已經暫停了兩個容器，現在使用unpause取消暫停

WARNING! This will remove all stopped containers.
Are you sure you want to continue? [y/N] y
Total reclaimed space: 0B
刪除的時候會提示是否繼續，如果不想提示可以加-f引數，最終會輸出刪除結果。
rename
重新命名一個容器
docker container rename CONTAINER NEW_NAME
or
docker rename CONTAINER NEW_NAME
檢視容器
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

stop
停止一個或多個正在執行的容器
docker container stop [OPTIONS] CONTAINER [CONTAINER...]
docker stop [OPTIONS] CONTAINER [CONTAINER...]
Options:
-t, --time int Seconds to wait for stop before killing it (default 10)
從引數上看，停止命令與重啟命令一樣，可以設定時間。
docker stop 30c33d778412
docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
30c33d778412 4b "catalina.sh run" 46 minutes ago Exited (143) 13 seconds ago test_name

從結果看出PORTS列，停止掉的容器已經是空的，表示容器已經停止成功。
update
更新一個或多個容器配置
docker container update [OPTIONS] CONTAINER [CONTAINER...]
or
docker update [OPTIONS] CONTAINER [CONTAINER...]
Options:
--blkio-weight uint16 Block IO (relative weight), between 10 and 1000, or 0 to disable (default 0)
--cpu-period int Limit CPU CFS (Completely Fair Scheduler) period
--cpu-quota int Limit CPU CFS (Completely Fair Scheduler) quota
--cpu-rt-period int Limit the CPU real-time period in microseconds
--cpu-rt-runtime int Limit the CPU real-time runtime in microseconds
-c, --cpu-shares int CPU shares (relative weight)
--cpus decimal Number of CPUs
--cpuset-cpus string CPUs in which to allow execution (0-3, 0,1)
--cpuset-mems string MEMs in which to allow execution (0-3, 0,1)
--kernel-memory bytes Kernel memory limit
-m, --memory bytes Memory limit
--memory-reservation bytes Memory soft limit
--memory-swap bytes Swap limit equal to memory plus swap: '-1' to enable unlimited swap
--pids-limit int Tune container pids limit (set -1 for unlimited)
--restart string Restart policy to apply when a container exits
從引數上看，可以更新容器的cpu、記憶體配置，需要注意的是，--kernel-memory自Docker 20.10起，該選項已被棄用。
wait
等待到一個或多個容器停止，然後列印容器的退出程式碼
docker container wait CONTAINER [CONTAINER...]
or
docker wait CONTAINER [CONTAINER...]
如果是一個已經停止的容器，則直接輸出退出的程式碼
docker wait 30c33d778412
143
指定一個正在執行的容器，會一直等待容器停止，然後輸出退出程式碼。
docker wait 8efed1c23ff5
啟動另外一個視窗，停止8efed1c23ff5容器，這個時候之前wait命令的視窗就輸出143的容器退出程式碼。
