Building Go app with "vendor" directory on Jenkins with Docker

问题

我正在尝试设置一个Jenkins Pipeline，使用一个Jenkinsfile和docker.image().inside来构建和部署我的第一个Go项目。我无法弄清楚如何让Go在vendor/目录中找到依赖项。

当我运行构建时，会出现一堆错误：

  1. + goapp test ./...
  2. src/dao/demo_dao.go:8:2: cannot find package "github.com/dgrijalva/jwt-go" in any of:
  3. 	/usr/lib/go_appengine/goroot/src/github.com/dgrijalva/jwt-go (from $GOROOT)
  4. 	/usr/lib/go_appengine/gopath/src/github.com/dgrijalva/jwt-go (from $GOPATH)
  5. 	/workspace/src/github.com/dgrijalva/jwt-go

为什么它没有找到vendor目录呢？

当我添加一些日志记录时，似乎在运行sh "cd /workspace/src/bitbucket.org/nalbion/go-demo"之后，下一个sh命令仍然在原始的${WORKSPACE}目录中。我很喜欢Jenkins文件的想法，但是我找不到任何合适的文档。

（编辑 - 这里有一份不错的文档here，但是dir("/workspace/src/bitbucket.org/nalbion/go-demo") {}在docker.image().inside中似乎不起作用）

我的Docker文件如下：

  1. FROM golang:1.6.2
  2. # Google's App Engine Go SDK
  3. RUN wget https://storage.googleapis.com/appengine-sdks/featured/go_appengine_sdk_linux_amd64-1.9.40.zip -q -O go_appengine_sdk.zip && \
  4.     unzip -q go_appengine_sdk.zip -d /usr/lib/ && \
  5.     rm go_appengine_sdk.zip
  6. ENV PATH /usr/lib/go_appengine:/go/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  7. ENV GOPATH /usr/lib/go_appengine/gopath
  8. # Add Jenkins user
  9. RUN groupadd -g 132 jenkins && useradd -d "/var/jenkins_home" -u 122 -g 132 -m -s /bin/bash jenkins

我的Jenkinsfile如下：

  1. node('docker') {
  2.     currentBuild.result = "SUCCESS"
  4.     try {
  5.         stage 'Checkout'
  6.         checkout scm
  8.         stage 'Build and Test'
  9.         env.WORKSPACE = pwd()
  10.         docker.image('nalbion/go-web-build:latest').inside(
  11.                 "-v ${env.WORKSPACE}:/workspace/src/bitbucket.org/nalbion/go-demo " +
  12.                 "-e GOPATH=/usr/lib/go_appengine/gopath:/workspace") {
  14.             // Debugging
  15.             sh 'echo GOPATH: $GOPATH'
  16.             sh "ls -al /workspace/src/bitbucket.org/nalbion/go-demo"
  17.             sh "cd /workspace/src/bitbucket.org/nalbion/go-demo"
  18.             sh "pwd"
  20.             sh "go vet ./src/..."
  21.             sh "goapp test ./..."
  22.         }
  24.         stage 'Deploy to DEV'
  25.         docker.image('nalbion/go-web-build').inside {
  26.             sh "goapp deploy --application go-demo --version v${v} app.yaml"
  27.         }
  29.         timeout(time:5, unit:'DAYS') {
  30.             input message:'Approve deployment?', submitter: 'qa'
  31.         }
  33.         stage 'Deploy to PROD'
  34.         docker.image('nalbion/go-web-build').inside {
  35.             sh "goapp deploy --application go-demo --version v${v} app.yaml"
  36.         }
  37.     } catch (err) {
  38.         currentBuild.result = "FAILURE"
  39.         // send notifications
  40.         throw err
  41.     }
  42. }

I'm trying to set up a Jenkins Pipeline to build and deploy my first Go project using a <code>Jenkinsfile</code> and <code>docker.image().inside </code>. I can't figure out how to get go to pick up the dependencies in the <code>vendor/</code> directory.

When I run the build, I get a bunch of errors:
<pre>

  • goapp test ./...
    src/dao/demo_dao.go:8:2: cannot find package "github.com/dgrijalva/jwt-go" in any of:
    /usr/lib/go_appengine/goroot/src/github.com/dgrijalva/jwt-go (from $GOROOT)
    /usr/lib/go_appengine/gopath/src/github.com/dgrijalva/jwt-go (from $GOPATH)
    /workspace/src/github.com/dgrijalva/jwt-go
    </pre>

...why isn't it picking up the Vendor directory?

When I throw in some logging, it seems that after running <code>sh "cd /workspace/src/bitbucket.org/nalbion/go-demo"</code> the next <code>sh</code> command is still in the original <code>${WORKSPACE}</code> directory. I really like the idea of the Jenkins file, but I can't find any decent documentation for it.

(Edit - there is decent documentation here but <code>dir("/workspace/src/bitbucket.org/nalbion/go-demo") {}</code> doesn't seem to work within <code>docker.image().inside)</code>

My Docker file resembles:
<pre>
FROM golang:1.6.2

Google's App Engine Go SDK

RUN wget https://storage.googleapis.com/appengine-sdks/featured/go_appengine_sdk_linux_amd64-1.9.40.zip -q -O go_appengine_sdk.zip &&
unzip -q go_appengine_sdk.zip -d /usr/lib/ &&
rm go_appengine_sdk.zip
ENV PATH /usr/lib/go_appengine:/go/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
ENV GOPATH /usr/lib/go_appengine/gopath

Add Jenkins user

RUN groupadd -g 132 jenkins && useradd -d "/var/jenkins_home" -u 122 -g 132 -m -s /bin/bash jenkins
</pre>

And my Jenkinsfile:
<pre>
node('docker') {
currentBuild.result = "SUCCESS"

  1. try {
  2.     stage &#39;Checkout&#39;
  3.     checkout scm
  5.     stage &#39;Build and Test&#39;
  6.     env.WORKSPACE = pwd()
  7.     docker.image(&#39;nalbion/go-web-build:latest&#39;).inside(
  8.             &quot;-v ${env.WORKSPACE}:/workspace/src/bitbucket.org/nalbion/go-demo &quot; +
  9.             &quot;-e GOPATH=/usr/lib/go_appengine/gopath:/workspace&quot;) {
  11.         // Debugging
  12.         sh &#39;echo GOPATH: $GOPATH&#39;
  13.         sh &quot;ls -al /workspace/src/bitbucket.org/nalbion/go-demo&quot;
  14.         sh &quot;cd /workspace/src/bitbucket.org/nalbion/go-demo&quot;
  15.         sh &quot;pwd&quot;
  17.         sh &quot;go vet ./src/...&quot;
  18.         sh &quot;goapp test ./...&quot;
  19.     }
  21.     stage &#39;Deploy to DEV&#39;
  22.     docker.image(&#39;nalbion/go-web-build&#39;).inside {
  23.         sh &quot;goapp deploy --application go-demo --version v${v} app.yaml&quot;
  24.     }
  26.     timeout(time:5, unit:&#39;DAYS&#39;) {
  27.         input message:&#39;Approve deployment?&#39;, submitter: &#39;qa&#39;
  28.     }
  30.     stage &#39;Deploy to PROD&#39;
  31.     docker.image(&#39;nalbion/go-web-build&#39;).inside {
  32.         sh &quot;goapp deploy --application go-demo --version v${v} app.yaml&quot;
  33.     }
  34. } catch (err) {
  35.     currentBuild.result = &quot;FAILURE&quot;
  36.     // send notifications
  37.     throw err
  38. }

}
</pre>

我通过在同一个sh语句中包含cd命令来使其正常工作：

  1. docker.image('nalbion/go-web-build:latest')
  2.       .inside("-v ${env.WORKSPACE}:/workspace/src/bitbucket.org/nalbion/go-demo " +
  3.               "-e GOPATH=/usr/lib/go_appengine/gopath:/workspace") {
  4.    sh """
  5.        cd /workspace/src/bitbucket.org/nalbion/go-demo
  6.        go vet ./src/...
  7.        goapp test ./...
  8.       """
  9. }
英文:

I managed to get it working by including the <code>cd</code> in the same <code>sh</code> statement:

<pre>
docker.image('nalbion/go-web-build:latest')
.inside("-v ${env.WORKSPACE}:/workspace/src/bitbucket.org/nalbion/go-demo " +
"-e GOPATH=/usr/lib/go_appengine/gopath:/workspace") {
sh """
cd /workspace/src/bitbucket.org/nalbion/go-demo
go vet ./src/...
goapp test ./...
"""
}
</pre>
