docker,podman配置国内镜像国内源

一些国内镜像地址

1. Docker中国区官方镜像 , 221005好像不能用 registry.docker-cn.com

2. 网易, 221005能用 hub-mirror.c.163.com

3. 中国科技大学 , 221005好像不能用 docker.mirrors.ustc.edu.cn

4. 阿里云容器 生成自己的加速地址 登录：cr.console.aliyun.com/#/accelerat… 点击“创建我的容器镜像”，得到专属加速地址。

docker配置文件 /etc/docker/daemon.json

/etc/docker/daemon.json , 如果没有就创建一个

sudo touch /etc/docker/daemon.json

编辑

sudo vi /etc/docker/daemon.json

查看

sudo cat /etc/docker/daemon.json

文件格式如下

{
    "registry-mirrors": [
        "http://hub-mirror.c.163.com",
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com"
    ]
}

用脚本,不存在则创建

#!/bin/bash
test -d /etc/docker || mkdir -p /etc/docker
test -f /etc/docker/daemon.json || echo '
{
    "registry-mirrors": [
        "http://hub-mirror.c.163.com",
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com"
    ]
}
' | sudo tee /etc/docker/daemon.json

测试,查看信息

sudo docker run hello-world

sudo docker info

podman的配置文件 /etc/containers/registries.conf

• 全局配置文件: /etc/containers/registries.conf
• 用户配置文件: ~/.config/containers/registries.conf

备份原文件

sudo cp /etc/containers/registries.conf /etc/containers/registries.conf.bak

sudo cp /etc/containers/registries.conf /etc/containers/registries.conf.`date "+%Y-%m-%dT%H:%M:%S"`.bak

sudo cp /etc/containers/registries.conf /etc/containers/registries.conf.`date "+%Y%m%d%H%M%S"`.bak

sudo cp /etc/containers/registries.conf /etc/containers/registries.conf.`date "+%y%m%d%H%M%S"`.bak

[ -e /etc/containers/registries.conf.BackupDir ] || mkdir /etc/containers/registries.conf.BackupDir
sudo cp /etc/containers/registries.conf /etc/containers/registries.conf.BackupDir/registries.conf.`date "+%Y%m%d%H%M%S"`.bak

编辑

sudo vi /etc/containers/registries.conf

sudo vi ~/.config/containers/registries.conf

查看

sudo cat /etc/containers/registries.conf

sudo cat ~/.config/containers/registries.conf

sudo more /etc/containers/registries.conf

sudo less /etc/containers/registries.conf

其中prefix是pull的时候指定的镜像前缀，location是获取镜像的地址，如果不指定prefix则默认和location一致。insecure=true表示允许通过HTTP协议来获取镜像，对于私有化部署/内网测试环境下无https证书的环境来说很有帮助。

配置单个镜像源

使用中科大源

###  CentOS9原版 unqualified-search-registries
# unqualified-search-registries = ["registry.fedoraproject.org", "registry.access.redhat.com", "registry.centos.org", "quay.io", "docker.io"]

###  Fedora36原版 unqualified-search-registries
# unqualified-search-registries = ["registry.fedoraproject.org", "registry.access.redhat.com", "docker.io", "quay.io"]

###  Rocky9原版 unqualified-search-registries
# unqualified-search-registries = ["registry.fedoraproject.org", "registry.access.redhat.com", "registry.centos.org", "quay.io", "docker.io"]

###  AlmaLinux9原版 unqualified-search-registries
# unqualified-search-registries = ["registry.access.redhat.com", "registry.redhat.io", "docker.io"]

### 取消从默认地址搜索的仓库域名
unqualified-search-registries = ["docker.io"]

### 自定义搜索器
[[registry]]
### 仓库前缀
prefix = "docker.io"
### 加速器地址
location = "docker.mirrors.ustc.edu.cn"
### 允许通过http协议获取镜像
insecure = true

使用docker中国区的源

unqualified-search-registries = ["docker.io"]

[[registry]]
prefix = "docker.io"
location = "registry.docker-cn.com"
insecure = true

使用163源

unqualified-search-registries = ["docker.io"]

[[registry]]
prefix = "docker.io"
location = "hub-mirror.c.163.com"
insecure = true

使用阿里源

unqualified-search-registries = ["docker.io"]

[[registry]]
prefix = "docker.io"
location = "xxxxxx.mirror.aliyuncs.com"

配置多个镜像源

unqualified-search-registries = ["docker.io"]

[[registry]]
prefix = "docker.io"
location = "hub-mirror.c.163.com"
insecure = true

[[registry.mirror]]
location = "docker.mirrors.ustc.edu.cn"
insecure = true
[[registry.mirror]]
location = "hub-mirror.c.163.com"
insecure = true
[[registry.mirror]]
location = "registry.docker-cn.com"
insecure = true

用脚本配置

#!/bin/bash
[ -e /etc/containers/registries.conf.BackupDir ] || mkdir /etc/containers/registries.conf.BackupDir
sudo cp /etc/containers/registries.conf /etc/containers/registries.conf.BackupDir/registries.conf.`date "+%Y%m%d%H%M%S"`.bak
printf '
unqualified-search-registries = ["docker.io"]

[[registry]]
prefix = "docker.io"
location = "hub-mirror.c.163.com"
insecure = true
[[registry.mirror]]
location = "docker.mirrors.ustc.edu.cn"
insecure = true
[[registry.mirror]]
location = "hub-mirror.c.163.com"
insecure = true
[[registry.mirror]]
location = "registry.docker-cn.com"
insecure = true
' | sudo tee /etc/containers/registries.conf

测试,查看信息

sudo podman run hello-world

sudo podman info
