刪除鏡像

方法1

docker image rm 鏡像名:版本號[root@test4 doc]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE redis 4.0 191c4017dcdd 3 months ago 89.3MB [root@test4 doc]# docker image rm redis:4.0 Untagged: redis:4.0 Untagged: redis@sha256:2e03fdd159f4a08d2165ca1c92adde438ae4e3e6b0f74322ce013a78ee81c88d Deleted: sha256:191c4017dcdd3370f871a4c6e7e1d55c7d9abed2bebf3005fb3e7d12161262b8 Deleted: sha256:c608627e4978ced00e2f061ae0386fab2e374376b96512bbbd2eea112b1c18ec Deleted: sha256:3fb5c9513585182e703038a67d9aaac987d4be30b6d3ece92ffe35734b330500 Deleted: sha256:e3a7fbb7bf3b4de87e6765498bf952b114f9bf297e5e93f51bd6a9a32083f8e4 Deleted: sha256:09f9b5d7722b181ae2acd61396c20549afdea66ee31f921850191db5afe6738a Deleted: sha256:3bd2921d0d3dd52dbcdc462f35b11cb89df901205284b0fea03c19bb8359907a Deleted: sha256:c2adabaecedbda0af72b153c6499a0555f3a769d52370469d8f6bd6328af9b13

方法2

[root@test4 doc]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE redis 4.0 191c4017dcdd 3 months ago 89.3MB [root@test4 doc]# docker rmi 191c4017dcdd Untagged: redis:4.0 Untagged: redis@sha256:2e03fdd159f4a08d2165ca1c92adde438ae4e3e6b0f74322ce013a78ee81c88d Deleted: sha256:191c4017dcdd3370f871a4c6e7e1d55c7d9abed2bebf3005fb3e7d12161262b8 Deleted: sha256:c608627e4978ced00e2f061ae0386fab2e374376b96512bbbd2eea112b1c18ec Deleted: sha256:3fb5c9513585182e703038a67d9aaac987d4be30b6d3ece92ffe35734b330500 Deleted: sha256:e3a7fbb7bf3b4de87e6765498bf952b114f9bf297e5e93f51bd6a9a32083f8e4 Deleted: sha256:09f9b5d7722b181ae2acd61396c20549afdea66ee31f921850191db5afe6738a Deleted: sha256:3bd2921d0d3dd52dbcdc462f35b11cb89df901205284b0fea03c19bb8359907a Deleted: sha256:c2adabaecedbda0af72b153c6499a0555f3a769d52370469d8f6bd6328af9b13

鏡像遷移

將鏡像打包成文件

docker save 鏡像名稱 | gzip > alpine-latest.tar.gz

將文件加載到docker

docker load -i alpine-latest.tar.gz

Docker Redis 使用

啟動redis

# 控制臺啟動redis # -d 是后臺運行 # -p :端口映射（-p 80:80）80端口映射到外部的80端口上，前一個是映射，后一個容器內的端口 docker run -p 6379:6379 [-d] redis:4.0 redis-server

?查看docker啟動的服務

[root@test4 ]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0cab60f2e5ae redis:4.0 "docker-entrypoint.s…" About a minute ago Up About a minute 0.0.0.0:6379->6379/tcp elegant_stonebraker

?調用客戶端使用服務

# 0cab60f2e5ae 是docker運行的 CONTAINER ID # /bin/bash 是進入容器，可以使用bash命令，比如使用redis-cli.sh [root@test4 doc]# docker exec -it 0cab60f2e5ae /bin/bash root@0cab60f2e5ae:/data# redis-cli 127.0.0.1:6379> KEYS * (empty list or set) 127.0.0.1:6379> set 1 1 OK 127.0.0.1:6379> get 1 "1" 127.0.0.1:6379>

查看容器日志

docker logs -f 容器名稱/容器ID

啟動和停止容器

啟動和停止容器中的數據不會變化，如果停止后再次執行 docker run -p 6379:6379 -d redis:4.0 redis-server 則會產生新的容器

單獨執行 stop start 指定的容器是不會發生變化

docker container stop 容器名稱/容器IDdocker container start 容器名稱/容器ID

?刪除容器

刪除之后就不能進行容器啟動和停止了

docker container rm 容器ID

?
