在谷歌云构建中使用 git 容器进行 git commit

Question

我在玩谷歌云构建。在我的用例中，我必须在构建过程中更改一个文件并将其提交到 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 来说是一种仪式。

你有什么建议如何缩短这些东西吗？

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", "batman@gotham.city" ]
- 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']

Push to Private Google repositories

尝试放 by command像这样:

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 batman@gotham.city
        git add -A
        git commit -m 'batmans commit'
        git push 'https://source.developers.google.com/p/$PROJECT_ID/r/my-repo' master

或者把它们放在 script file像这样:

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

或换 alpine 至 python 像这样:

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

或者使用 config elements 写它像这样:

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

然后把你所有的 build steps在 git.sh文件:

#!bin/sh
sh ./some-file.txt
git config --global user.name batman
git config --global user.email batman@gotham.city
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

Push to Private GitHub repositories

如果您想将 repo 推送到 Github，您可以使用 kms service 运行构建器连同 ssh-agent and or expect .然后模拟 git interaction to private GitHub repositories像这样:

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，您也可以放置步骤 resource在 git.sh文件:

#!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 'git@github.com:my-user/my-repo.git'
git push origin master

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

当您设置 mirror configuration 然后，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。
