在Golang中使用Docker客户端创建服务(Service)时,可以通过设置RegistryAuth
来指定私有注册中心。下面是一个示例代码:
package main
import (
"context"
"fmt"
"github.com/docker/docker/api/types"
"github.com/docker/docker/client"
)
func main() {
cli, err := client.NewClientWithOpts(client.FromEnv)
if err != nil {
panic(err)
}
authConfig := types.AuthConfig{
Username: "your_username",
Password: "your_password",
ServerAddress: "your_registry_url",
}
authConfigBytes, _ := json.Marshal(authConfig)
base64Auth := base64.URLEncoding.EncodeToString(authConfigBytes)
spec := types.ServiceSpec{
TaskTemplate: types.TaskSpec{
ContainerSpec: &types.ContainerSpec{
Image: "your_image_name",
Command: []string{"your_command"},
},
RestartPolicy: &types.RestartPolicy{
Condition: types.RestartPolicyConditionNone,
},
Payload: &types.ContainerPayload{
Mounts: []mount.Mount{},
},
Runtime: "container",
ServiceRegistry: &types.ServiceRegistryOptions{Base64AuthString: base64Auth},
LogDriverOptions: map[string]string{},
ResourceLimits: &units.ResourceObject{
NanoCPUs: 1000000000,
MemoryBytes: 536870912,
},
LoggingDriverOptionsMap:
map[string]map[string]string{},
},
}
serviceCreateResponse, err := cli.ServiceCreate(context.Background(), spec, types.ServiceCreateOptions{})
if err != nil {
panic(err)
}
fmt.Println(serviceCreateResponse.ID)
}
在上述代码中,你需要将your_username
、your_password
和your_registry_url
替换为你私有注册中心的用户名、密码和URL。另外,还需设置好你想要创建服务的镜像名、命令等相关信息。
请注意,此示例假设已经安装了Docker Go SDK,并已导入必要的包。
