GitLab CI 对 Docker 构建作业的无效参数 [英] GitLab CI invalid argument on job for Docker build

问题描述

所以我正在尝试设置我的 Gitlab CI 以触发 git push 上的作业以构建和部署我的 Docker.这是我使用的 .gitlab-ci.yml 文件，基于 Gitlab 文档 (Elixir yml) 中的示例.

So I'm trying to setup my Gitlab CI to trigger a job on git push to build and deploy my Docker. This is the .gitlab-ci.yml file I'm using based on an example from Gitlab docs (Elixir yml).

stages:
  - build

build:
  before_script:
    - docker build -f Dockerfile.build -t ci-project-build-$CI_PROJECT_ID:$CI_BUILD_REF .
    - docker create
      -v /build/deps 
      -v /build/_build
      -v /build/rel
      -v /root/.cache/aceapp/
      --name build_data_$CI_PROJECT_ID_$CI_BUILD_REF busybox /bin/true
  tags:
    - docker
  stage: build
  script: 
    - docker run --volumes-from build_data_$CI_PROJECT_ID_$CI_BUILD_REF --rm -t ci-project-build-$CI_PROJECT_ID:$CI_BUILD_REF

推送到 GitLab 实例时的输出是这样的:

The output when pushing to GitLab instance is this:

我了解 docker 标签无效(before_script: 真的是根据名称触发的吗?)，我正在寻求有关 a) 解决方案 b) 我如何学习的帮助更多关于基于默认设置构建 docker 的管道的要求.我是否需要在本地标记我的 docker 映像，然后以某种方式将其添加到我的 git 提交中?

I understand the docker tag is not valid (is the before_script: really triggered based on the name?), and I'm looking for help regarding a) a solution b) how I can learn more about the requirements for a pipeline that builds docker based on default settings. Do I need to tag my docker image locally and then somehow add this to my git commit?

推荐答案

-t 就是标记你的 Docker 镜像.查看文档这里.

The thing is -t is to tag your Docker image. See the docs here.

标签的格式应该像 name:version，并且你给它 /master:9fa2d4358e6c426b882e2251aa5a49880013614b 这不是一个有效的标签.您可以尝试在 master

The tag should be formated like name:version, and you giving it /master:9fa2d4358e6c426b882e2251aa5a49880013614b which is not a valid tag. You could try to delete the / before master
