如何在设置中启动docker容器

Question

我创建了一个DroneCI管道，内容如下：

kind: pipeline
type: docker
name: Build auto git tagger
steps:
- name: test and build
image: golang
commands:
- go mod download
- go test ./test
- go build -o ./build/package ./cmd/git-tagger
- name: Build docker image
image: plugins/docker
pull: if-not-exists
settings:
username: 
password: 
repo: 
dockerfile: 
registry: 
auto_tag: 
trigger:
branch:
- master

go test启动gogs docker容器进行测试，代码如下：

func createGogsContainer(dest, waitUrl string) (stopContainer, error) {
client, err := docker.NewClientFromEnv()
if err != nil {
return nil, err
}
ctx := context.Background()
gogs, err := client.CreateContainer(docker.CreateContainerOptions{
Name: "repo",
Config: &docker.Config{
Image: "gogs/gogs",
},
HostConfig: &docker.HostConfig{
PublishAllPorts: true,
AutoRemove:      true,
Mounts: []docker.HostMount{
{
Type:   "bind",
Source: dest,
Target: "/data",
}},
PortBindings: map[docker.Port][]docker.PortBinding{
"3000/tcp": {{HostIP: "0.0.0.0", HostPort: "8888"}},
"22/tcp":   {{HostIP: "0.0.0.0", HostPort: "2222"}},
},
},
Context: ctx,
})
if err != nil {
return nil, err
}
err = client.StartContainer(gogs.ID, nil)
if err != nil {
return nil, err
}
//Wait for connection
host, err := url.Parse(waitUrl)
if err != nil {
return nil, err
}
err = waitHTTP(fmt.Sprintf("%s://%s", host.Scheme, host.Host), 3, 0)
if err != nil {
return nil, err
}
return func() error {
return client.StopContainerWithContext(gogs.ID, 5, ctx)
}, nil
}  

管道已中止，并显示以下错误消息：

我做错了什么？

Answer 1

看看无人机服务。它允许您将容器作为管道的一部分，并访问其端口。

在你的情况下，你可以像这样打开Gogs容器：

services:
- name: gogs
image: gogs/gogs

然后在你的管道步骤中这样使用它：

steps:
- name: test and build
image: golang
commands:
- curl "http://gogs"
-
...

(这假定gogs容器在端口80上侦听。如果是不同的端口，则需要调整URI(。

提示：服务的名称是容器的DNS名称。
