Docker安装
Centos7.9为例
yum源更新
- 更新为阿里云yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo或者
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo curl -o /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo - 清理并重新生成缓存
yum clean all yum makecache - 配置docker-ce源为阿里云
# step 1: 安装必要的一些系统工具 yum install -y yum-utils device-mapper-persistent-data lvm2 # Step 2: 添加软件源信息 yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # Step 3 sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo # Step 4: 更新并安装Docker-CE yum makecache fast yum -y install docker-ce # Step 4: 开启Docker服务 service docker start - 安装docker-ce及其依赖
yum install -y docker-ce
buildx driver配置
buildx配置文件buildkitd.toml，支持私服http连接
debug = true
# insecure-entitlements allows insecure entitlements, disabled by default.
insecure-entitlements = [ "network.host", "security.insecure" ]
# optionally mirror configuration can be done by defining it as a registry.
[registry."registryUrl"]
http = true
insecure = true
执行配置
docker buildx create --name=mybuilder --use --driver-opt image=registry/buildkit:buildx-stable-1 --config /buildkitd.toml
启动buildx容器
docker buildx inspect --bootstrap mybuilder
多平台镜像构建
构建命令
docker buildx build -t registryUrl/xxx:v1 --platform=linux/arm64,linux/amd64 -o type=image,push=true ./
