使用 multipass+autok3s 搭建本地 k8s 集群（下）

mkdir test
cd test
# 这是最后要验证的结果
cat >> index.html << EOF

EOF
# 基于 nginx 镜像，把这个文件拷进去
cat >> Dockerfile << EOF
FROM nginx
COPY index.html /usr/share/nginx/html/

# 构建镜像
podman build . -t docker.imac.local/test-app
# push 到我们的私有 registry 中
podman push docker.imac.local/test-app --tls-verify=false
