git - 在谷歌云构建中使用 git 容器进行 git commit

Question

我正在玩 Google Cloud Build。在我的用例中，我必须在构建期间更改文件并将其提交到 git 中。

我绘制了如下所示的构建步骤，它们确实有效。但这对于做一个简单的 git commit 来说是很多仪式。

你对如何缩短这些东西有什么建议吗？

steps:
- name: alpine
  args: ["touch", "some-file.txt"]
- name: gcr.io/cloud-builders/git
  args: [ "config", "--global", "user.name", "batman" ]
- name: gcr.io/cloud-builders/git
  args: [ "config", "--global", "user.email", "[e-mail]" ]
- name: gcr.io/cloud-builders/git
  args: [ "add", "-A" ]
- name: gcr.io/cloud-builders/git
  args: [ 'commit', '-m', 'batmans commit' ]
- name: gcr.io/cloud-builders/git
  args: [ 'push', 'https://source.developers.google.com/p/$PROJECT_ID/r/my-repo', 'master']

推送到私人 Google 存储库

尝试通过这样的命令放置：

steps:
- name: 'gcr.io/cloud-builders/git'
  entrypoint: 'bash'
  args:
  - '-c'
  - |
        touch ./some-file.txt
        git config --global user.name batman
        git config --global user.email [e-mail]
        git add -A
        git commit -m 'batmans commit'
        git push 'https://source.developers.google.com/p/$PROJECT_ID/r/my-repo' master

或者将它们放在这样的脚本文件中：

steps:
- name: gcr.io/cloud-builders/git
  args: ["sh", "git.sh"]

或者改成alpine这样python：

steps:
- name: python
  args: ["sh", "git.sh"]

或者使用这样的配置元素编写它：

steps:
- name: python
  entrypoint: /bin/sh
  args: ['-c', './git.sh]

然后将所有构建步骤放入git.sh文件中：

#!bin/sh
sh ./some-file.txt
git config --global user.name batman
git config --global user.email [e-mail]
git add -A
git commit -m 'batmans commit'
git remote set-url origin 'https://source.developers.google.com/p/$PROJECT_ID/r/my-repo'
git push origin master

推送到私有 GitHub 存储库

如果您想将 repo 推送到 Github，您可以kms service使用ssh-agentand 或expect运行构建器。然后模拟git 与私有 GitHub 存储库的交互，如下所示：

steps:
- name: 'gcr.io/cloud-builders/gcloud'
  args: ['kms', 'decrypt', '--location', 'global', 
         '--keyring', 'my-keyring','--key', 'github-key', 
         '--ciphertext-file', 'id_rsa.enc', '--plaintext-file', '/root/.ssh/id_rsa'] 
  volumes:
  - name: 'ssh'
    path: /root/.ssh

- name: 'python'
  entrypoint: 'bash'
  args: ['-c', './git.sh]
  volumes:
  - name: 'ssh'
    path: /root/.ssh

与上面类似，您可以将步骤也资源放在git.sh文件中：

#!bin/sh
chmod 600 /root/.ssh/id_rsa
cat <<EOF >/root/.ssh/config
Hostname github.com
IdentityFile /root/.ssh/id_rsa
EOF
mv known_hosts /root/.ssh/known_hosts
apt-get update
apt-get --assume-yes install expect
git config --global <github:user.name>
git config --global <github:user.email>
eval `ssh-agent` && expect agent_builder && ssh-add -l
cd /path/to/my-repo
git add .
git commit -m 'batmans commit'
git remote set-url origin '[e-mail]:my-user/my-repo.git'
git push origin master

该文件agent_builder包含以下代码：

#!/usr/bin/expect -f
spawn ssh-add /root/.ssh/id_rsa
expect "Enter passphrase for /root/.ssh/id_rsa:"
send "my-passphrase\n";
expect "Identity added: /root/.ssh/id_rsa (/root/.ssh/id_rsa)"
interact

设置mirror configuration后，您推送到 GitHub 存储库的提交将被复制或镜像回托管在 Cloud Source Repositories 中的 Google 存储库。
