[Centos8] The bumpy process of installing docker
Because I need to use docker to get a redis cluster, I went to install it.
Important steps##
Try the water first
Then found out that this is not possible.
yum install docker, some people say so, but it doesn't work.
Some people say: curl -fsSL https://get.docker.com | bush -s docker – mirror Aliyun
Still reporting an error.
But victory is in sight,
Don't be angry at this time, don't be discouraged, cross this hurdle.
first step##
[Problem solving] package docker-ce-3:19.03.11-3.el7.x86_64 requires containerd.io greater than or equal to 1.2.2-3 but none of...
problem causes:
There is no containerd.io in the yum library of centos8 that conforms to the latest version of docker-ce. docker-ce-3:19.03.11-3.el7.x86_64 requires containerd.io >= 1.2.2-3
solution:
Install the latest docker through Alibaba Cloud image library-ce version of containerd.io
yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.13-3.2.el7.x86_64.rpm
sudo yum -y install docker-ce docker-ce-cli
Are you scared?
It's useless to be afraid, it will fail or fail.
Step two##
sudo yum -y install docker-ce docker-ce-cli --allowerasing
Come again if you fail
third step##
curl -sSL https://get.daocloud.io/docker | sh
If you want to use the previous Alibaba Cloud, you can change it
the fourth step##
docker version
See if the installation is successful
the fifth step##
Start docker
systemctl start docker
Everything is so natural
