使用 GitHub Actions 在作业之间共享构建的镜像
由于每个作业都隔离在其自己的运行器中,因此您无法使用构建的镜像 在作业之间,除非您使用的是自托管运行器但是,您可以使用 actions/upload-artifact 和 actions/download-artifact 操作在工作流程中的作业之间传递数据:
name: ci
on:
push:
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Set up Docker Buildx
uses: docker/setup-buildx-action@v3
- name: Build and export
uses: docker/build-push-action@v6
with:
tags: myimage:latest
outputs: type=docker,dest=/tmp/myimage.tar
- name: Upload artifact
uses: actions/upload-artifact@v4
with:
name: myimage
path: /tmp/myimage.tar
use:
runs-on: ubuntu-latest
needs: build
steps:
- name: Download artifact
uses: actions/download-artifact@v4
with:
name: myimage
path: /tmp
- name: Load image
run: |
docker load --input /tmp/myimage.tar
docker image ls -a
