Git预提交钩子

Question

我需要在 Docker 镜像中设置一系列 Gitlab 钩子，以便在 pre-commit 时触发。我有一个 Docker 文件和一个 pre-commit-config.yaml 文件，其中除了一个无法正常工作的钩子外，其余都可以成功构建。

repos:
  - repo: local
    hooks:
      - id: check-merge-conflict
        name: Check for merge conflicts
        description: Check for files that contain merge conflict strings.
        entry: check-merge-conflict
        language: python
        types: [text]

      - id: epp-validate
        additional_dependencies: ['puppet']
        description: Validate syntax of Puppet EPP templates
        entry: /puppet-pre-commit-hooks/epp-validate
        files: \.epp$
        language: ruby
        name: Validate EPP templates

      - id: erb-validate
        description: Validate syntax of Ruby ERB templates
        entry: /puppet-pre-commit-hooks/erb-validate
        files: \.erb$
        language: ruby
        name: Validate ERB templates

      - id: puppet-lint
        additional_dependencies: ['puppet-lint']
        description: Check Puppet manifests for stylistic problems
        entry: /puppet-pre-commit-hooks/puppet-lint
        files: \.pp$
        language: ruby
        name: puppet-lint
        args:
          - --fail-on-warnings

      - id: puppet-validate
        additional_dependencies: ['puppet']
        description: Validate syntax of Puppet manifests
        entry: /puppet-pre-commit-hooks/puppet-validate
        files: \.pp$
        language: ruby
        name: Validate Puppet manifests

      - id: r10k-validate
        additional_dependencies: ['r10k']
        description: Validate syntax of Puppetfile using r10k
        entry: /puppet-pre-commit-hooks/r10k-validate
        files: ^Puppetfile$
        language: ruby
        name: Validate r10k Puppetfile

      - id: ruby-validate
        additional_dependencies: ['ruby']
        description: Validate syntax of ruby code
        entry: /puppet-pre-commit-hooks/ruby-validate
        files: \.rb$
        language: ruby
        name: Validate ruby syntax

由于使用环境无法访问互联网，我不得不将钩子设置为本地钩子。为了解决这个问题，我克隆了一些具有适当钩子的存储库。

除了检查合并冲突钩子之外，它可以成功构建。在docker容器中，此钩子的python代码位于/pre-commit-hooks/pre_commit_hooks/check_merge_commit.py。

我尝试修改条目：值为 '''/pre-commit-hooks/pre_commit_hooks/check_merge_commit pre_commit_hooks/check-merge-commit check_merge_commit'''

但是这些都没有起作用。

Docker文件

FROM ruby:2.5.0

SHELL ["/bin/bash", "-o", "pipefail", "-c"]
RUN source ~/.profile
RUN curl https://pre-commit.com/install-local.py | python -
COPY pre-commit/.pre-commit-config.yaml .
RUN git clone https://github.com/pre-commit/pre-commit-hooks.git
RUN git clone https://github.com/chriskuehl/puppet-pre-commit-hooks.git
RUN git clone https://github.com/adrienverge/yamllint.git
WORKDIR /jumanjihouse
RUN git clone https://github.com/jumanjihouse/pre-commit-hooks.git
RUN rm -rf /jumanjihouse/pre-commit-hooks/.git* /yamllint/.git* /puppet-pre-commit-hooks/.git* /pre-commit-hooks/.git* /usr/local/lib/ruby/gems/2.5.0/gems/*/.git*
WORKDIR /
RUN git init
RUN /root/bin/pre-commit run -a

有人知道我漏掉了什么或者错了吗？

这个钩子来自于 Github

你提到你有一个空气隔离，但仍然从Github克隆 - 你可以使用正常配置并在你的Docker镜像内运行pre-commit install-hooks吗？这样你就可以在空气隔离的情况下使用该镜像，而无需在运行时安装任何东西。 - anthony sottile

没错！我们在 Lyft 也是这样做的 -- 你可以在外部运行 pre-commit install-hooks，并使用任何正常配置 -- 在运行时它不会使用网络。 - anthony sottile

所以如果我放置 RUN /root/bin/pre-commit install-hooks 应该可以工作，对吗？如果这是基础知识的话，对不起，但我对编写管道还是很新的。 - MmmmDonuts

没错！-- 并返回到原始配置（不需要local或手动克隆） - anthony sottile

你是个传奇，感谢你的付出，安东尼，真的非常感激。 - MmmmDonuts

如果您在构建过程中有克隆访问权限，您不需要手动克隆每个仓库并使用本地钩子程序的方式。为了确保所有的钩子程序都预先安装好，您需要在dockerfile中运行 pre-commit install-hooks 命令。这将确保所有的钩子可执行文件被正确缓存到您的镜像中，并且在后续运行 pre-commit run ... 时可用。

免责声明：我是 pre-commit 的作者。
