2.3 docker pull 命令

（1） docker pull 镜像名称 下载最新版的镜像 如下为下载最新版的mysql镜像

[root@localhost ~]# docker pull mysqlUsing default tag: latestlatest: Pulling from library/mysql07aded7c29c6: Pull completef68b8cbd22de: Pull complete30c1754a28c4: Pull complete1b7cb4d6fe05: Pull complete79a41dc56b9a: Pull complete00a75e3842fb: Pull completeb36a6919c217: Pull complete635b0b84d686: Pull complete6d24c7242d02: Pull complete5be6c5edf16f: Pull completecb35eac1242c: Pull completea573d4e1c407: Pull completeDigest: sha256:4fcf5df6c46c80db19675a5c067e737c1bc8b0e78e94e816a778ae2c6577213dStatus: Downloaded newer image for mysql:latestdocker.io/library/mysql:latest[root@localhost ~]#

如下，可以看到显示已经下载完成的mysql镜像版本为latest

[root@localhost ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEmysql latest 2fe463762680 11 days ago 514MBhello-world latest feb5d9fea6a5 2 weeks ago 13.3kB[root@localhost ~]#

（2）docker pull 镜像名称:tag 下载指定版本的镜像 如下为指定下载5.7版本的mysql

[root@localhost ~]# docker pull mysql:5.75.7: Pulling from library/mysql07aded7c29c6: Already existsf68b8cbd22de: Already exists30c1754a28c4: Already exists1b7cb4d6fe05: Already exists79a41dc56b9a: Already exists00a75e3842fb: Already existsb36a6919c217: Already exists5e11fe494f45: Pull complete9c7de1f889a7: Pull completecf6a13d05a76: Pull completefc5aa81f393a: Pull completeDigest: sha256:360c7488c2b5d112804a74cd272d1070d264eef4812d9a9cc6b8ed68c3546189Status: Downloaded newer image for mysql:5.7docker.io/library/mysql:5.7[root@localhost ~]#
