  ],
  "max-concurrent-downloads": 10,
  "max-concurrent-uploads": 5,
  "live-restore":true,
  "log-driver": "json-file",
  "log-opts": {
  	"max-size": "100m",
	"max-file":"5"
  },
  "storage-driver": "overlay2",
  "storage-opts": [
  	"overlay2.override_kernel_check=true"
  ],

1.5 国内加速 ​

yaml
{
  "registry-mirrors": [
	  "https://docker.anyhub.us.kg",
	  "https://dockerhub.icu",
	  "https://docker.awsl9527.cn",
	  "https://gcr.chenby.cn",
	  "https://k8s.chenby.cn",
	  "https://docker.chenby.cn" 
  ]
}
{
  "registry-mirrors": [
	  "https://docker.anyhub.us.kg",
	  "https://dockerhub.icu",
	  "https://docker.awsl9527.cn",
	  "https://gcr.chenby.cn",

  ]
}

2. aws ​

https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/install-docker.html

  • To install Docker on Amazon Linux 2 or Amazon Linux 2023

  1. Update the installed packages and package cache on your instance.

    $ sudo yum update -y
    $ sudo yum update -y

  2. Install the most recent Docker Community Edition package.

    • For Amazon Linux 2, run the following:

      $ sudo amazon-linux-extras install docker
      $ sudo amazon-linux-extras install docker

    • For Amazon Linux 2023, run the following:

      $ sudo yum install -y docker
      $ sudo yum install -y docker

  3. Start the Docker service.

    $ sudo service docker start
    $ sudo service docker start

  4. Add the ec2-user to the docker group so that you can run Docker commands without using sudo.

    $ sudo usermod -aG docker ec2-user
    $ sudo usermod -aG docker ec2-user

3. RockLinux ​

3.1 卸载 ​

 dnf remove podman # 或者 sudo yum remove podman
 dnf remove podman # 或者 sudo yum remove podman

3.2 删除残留文件 ​

rm -rf /etc/containers /etc/registries.conf /etc/containers/policy.json /etc/containers/storage.conf ~/.config/containers ~/.local/share/containers
rm -rf /etc/containers /etc/registries.conf /etc/containers/policy.json /etc/containers/storage.conf ~/.config/containers ~/.local/share/containers

3.3 卸载旧版docker ​

dnf remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
dnf remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
