CentOS 8：如何更新 Docker 客户端

Question

我之前在我的 CentOS 8 中安装了 docker，现在我正在尝试更新。

此回答中描述了我的更新步骤

sudo rpm -Uvh https://download.docker.com/linux/centos/8/x86_64/stable/Packages/containerd.io-1.4.6-3.1.el8.x86_64.rpm
sudo rpm -Uvh https://download.docker.com/linux/centos/8/x86_64/stable/Packages/docker-ce-cli-20.10.7-3.el8.x86_64.rpm
sudo rpm -Uvh https://download.docker.com/linux/centos/8/x86_64/stable/Packages/docker-ce-20.10.7-3.el8.x86_64.rpm

但是检查我的版本...

或者

$ docker -v
Docker version 19.03.12, build 48a66213fe
$

如何更新客户端？

$

我的步骤

$ rpm -qa | grep containerd
containerd.io-1.4.6-3.1.el8.x86_64
$

我尝试卸载

$ rpm -evh containerd
error: package containerd is not installed
$

我们再试一次

$ rpm -evh containerd.io-1.4.6-3.1.el8.x86_64
error: Failed dependencies:
    containerd.io >= 1.4.1 is needed by (installed) docker-ce-3:20.10.7-3.el8.x86_64
$

让我们检查一下 docker-ce。

$ rpm -qa | grep docker-ce
docker-ce-cli-20.10.7-3.el8.x86_64
docker-ce-rootless-extras-20.10.7-3.el8.x86_64
docker-ce-20.10.7-3.el8.x86_64
$

去删除它

$ rpm -evh docker-ce-20.10.7-3.el8.x86_64
error: Failed dependencies:
    docker-ce is needed by (installed) docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64
$

然后

$ rpm -evh docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64
error: Failed dependencies:
    docker-ce-rootless-extras is needed by (installed) docker-ce-3:20.10.7-3.el8.x86_64
$

再次尝试同时删除：docker-ce 和 docker-ce-rootless-extras！

$ sudo rpm -evh docker-ce-20.10.7-3.el8.x86_64 docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64

我去删除docker-ce-cli

$ rpm -evh docker-ce-cli-20.10.7-3.el8.x86_64
error: Failed dependencies:
    docker-ce-cli is needed by (installed) docker-scan-plugin-0:0.8.0-3.el7.x86_64
$

让我们同时删除：docker-ce-cli 和 docker-scan-plugin。

$ sudo rpm -evh docker-ce-cli-20.10.7-3.el8.x86_64 docker-scan-plugin-0:0.8.0-3.el7.x86_64

现在安装 docker-ce-cli 和 docker-scan-plugin

可惜我有相同版本的客户端！

Answer 1

使用搜索工具检查其中的文件并查找哪些文件具有 docker 的 19.03.12 版本以进行卸载。

发现了许多内容为“19.03.12”的文件，但最可疑的文件位于 $HOME/bin 目录：

docker
dockerd

我在

上找到了一些文件

$ ls ~/bin
containerd  containerd-shim  ctr  docker  dockerd  dockerd-rootless.sh  docker-init  docker-proxy  rootlesskit  rootlesskit-docker-proxy  runc  vpnkit
$

Maybe just deleting or renaming those files would have been enough (without having to uninstall or reinstall everything), but I didn't test at the time.

我又全部卸载了:

$ sudo rpm -evh \
containerd.io-1.4.6-3.1.el8.x86_64 \
docker-ce-20.10.7-3.el8.x86_64 \
docker-ce-rootless-extras-0:20.10.7-3.el8.x86_64 \
docker-ce-cli-20.10.7-3.el8.x86_64 \
docker-scan-plugin-0.8.0-3.el8.x86_64

我重命名了可疑文件（我几乎重命名了所有文件，尽管有些可能是不必要的）。

$ ls $HOME/bin
containerd_OLD  containerd-shim_OLD  ctr  dockerd_OLD  dockerd-rootless.sh_OLD  docker-init_OLD  docker_OLD  docker-proxy_OLD  rootlesskit-docker-proxy_OLD  rootlesskit_OLD  runc_OLD  vpnkit
$

全部重新安装

$ sudo rpm -Uvh \
https://download.docker.com/linux/centos/8/x86_64/stable/Packages/containerd.io-1.4.6-3.1.el8.x86_64.rpm \
