docker - Docker 未被识别为内部或外部命令

问题描述

我有以下 .gitlab-ci.yml 文件：

image: docker:latest

variables:
 DOCKER_DRIVER: overlay2

services:
 - docker:dind

before_script:
 - docker info

stages:
 - deploy

step-deploy-dev:
 stage: deploy
 script:
  - echo build and deploy
  - docker build -t myimage myproject/.
  - echo finished build and deploy..
 environment: master

有时（我无法确定原因）我收到以下错误：

Running with gitlab-runner 10.8.0 (079aad9e)
  on My-CI de8391de

解决方案

在您看到此错误的情况下，您的作业在配置了错误执行器的运行器上运行。您的工作需要使用 docker 执行器的运行器。

您可以在输出中看到它说：

Using Shell executor...

应该说

Using Docker executor with image docker:latest ...

您可以标记作业和 docker 运行器，以确保作业仅在所需的运行器上运行。当您注册跑步者时，请指定“docker”之类的标签，然后在作业配置中添加 tags 属性：

step-deploy-dev:
 stage: deploy
 script:
  - echo build and deploy
  - docker build -t myimage myproject/.
  - echo finished build and deploy..
 environment: master
 tags:
  - docker
