方法1: 为当前用户设置环境变量

您可以为当前用户设置 HTTP_PROXY 和 HTTPS_PROXY 环境变量,Podman 将自动读取这些环境变量并使用代理。

# Bash
export HTTP_PROXY="http://代理地址:端口"  
export HTTPS_PROXY="https://代理地址:端口"

# 对于 bash, 也可以在 ~/.bashrc 中添加上述命令使其永久有效

# Fish
set -x HTTP_PROXY "http://代理地址:端口"
set -x HTTPS_PROXY "https://代理地址:端口"

# 对于 fish,也可以在 ~/.config/fish/config.fish 中添加以上命令

如果您的代理需要身份验证,可以在 URL 中添加用户名和密码。格式如下:

http://用户名:密码@代理地址:端口

方法2：为 Podman 服务设置配置文件

您还可以通过编辑 /etc/containers/registries.conf 配置文件为 Podman 服务设置代理。在该文件中添加如下内容:

[registries.search]
registries = ['docker.io', 'quay.io']

[registries.insecure]
registries = []

[registries.block]
registries = []

[registries.unqualified-search-registries]

[registry.mirrors]

[registry.configs]

[registry.configs.REGISTRY_NAME.HOSTNAME/HOSTPATH]  
unqualified-search-registries = ["registry.fedoraproject.org", "registry.access.redhat.com", "docker.io"]
blocked=false 

[registry.configs.REGISTRY_NAME.HOSTNAME]
http-proxy="http://代理地址:端口"
https-proxy="https://代理地址:端口"

替换 REGISTRY_NAME.HOSTNAME 为您要配置的注册表,如 docker.io。如果代理需要身份验证,则使用类似 http://user:password@proxy.example.com:8080 的格式。

方法3: 为单个 Podman 命令设置代理

您也可以为单个 Podman 命令临时设置代理,方法是在命令前添加 --build-arg 参数。例如:

podman --build-arg HTTP_PROXY="http://代理地址:端口" --build-arg HTTPS_PROXY="https://代理地址:端口" pull nginx

方法四: 配置 http-proxy.conf
