多架构镜像如何制作

# 文件目录# bin目录是go程序编译结果 go build GOOS=linx GOARCH=amd64 \ GOARCH=arm64.├── Dockerfile├── README.md├── bin│   ├── amd64│   │   └── tool│   └── arm64│       └── tool├── golang│   ├── go.mod│   └── main.go└── sh    └── start.sh

# 基础架构就是支持多架构的 https://hub.docker.com/_/alpine/tagsFROM --platform=$TARGETPLATFORM alpine:3.18.4
WORKDIR /app
ARG TARGETPLATFORMARG TARGETARCH
# 将对应架构的go程序放在app目录COPY bin/$TARGETARCH/* /app
# 镜像启动脚本COPY sh/start.sh /app
RUN chmod +x /app/start.sh
# ENTRYPOINT无法被覆盖,CMD可以被覆盖,使用CMD是为了方便helm包安装镜像时候更改启动指令CMD ["/bin/sh","/app/start.sh"] 

# docker配置文件如下/root/.docker/config.json/etc/docker/daemon.json

# 创建一个新的 buildx 构建器，并将其设置为当前正在使用的构建器# 以便在运行 Docker 构建命令时可以使用该构建器进行构建# 通过 network=host 指定共享主机网络$ docker buildx create --name builder --config /etc/buildkit/buildkitd.toml \    --platform linux/arm64,linux/amd64 \    --append --driver-opt network=host --use
# 开始构建$ docker buildx build -t registry.my.net/develop/tool:v0.0.1 --platform=linux/arm64,linux/amd64 . --push

   {    "auths": {            "registry.my.net": {                "auth": "xxx"            }        }    }

   {        "insecure-registries" : [ "registry.my.net" ],        "experimental": true,         "features": {            "buildkit": true        }    }

   [registry."registry.my.net"]    http = true    insecure = true

# 先制作镜像$ docker images- registry.bingosoft.net/bingokube/etcd:v3.5.0-amd64- registry.bingosoft.net/bingokube/etcd:v3.5.0-arm64
# 制作清单$ docker manifest create --insecure registry.bingosoft.net/bingokube/etcd:v3.5.0 registry.bingosoft.net/bingokube/etcd:v3.5.0-amd64 registry.bingosoft.net/bingokube/etcd:v3.5.0-arm64
# 推送清单$ docker manifest push --insecure registry.bingosoft.net/bingokube/etcd:v3.5.0
# 查看清单$ docker manifest inspect registry.bingosoft.net/bingokube/etcd:v3.5.0{   "schemaVersion": 2,   "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",   "manifests": [      {         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",         "size": 1783,         "digest": "sha256:abc",         "platform": {            "architecture": "amd64",            "os": "linux"         }      },      {         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",         "size": 1576,         "digest": "sha256:abc",         "platform": {            "architecture": "arm64",            "os": "linux"         }      }   ]}
