Dockerfile COPY 失败：使用 GitHub CI 时统计没有这样的文件

Question

我正在使用 GitHub 项目的 Gradle 操作，步骤如下：

name: Java CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v1
      - name: Set up JDK 11
        uses: actions/setup-java@v1
        with:
          java-version: 11

      - run: gradle wrapper

      - run: ./gradlew bootJar

      - run: ls ./build/libs/

      - uses: actions/checkout@v1
      - name: Login to docker
        run: docker login docker.pkg.github.com -u xxxxxx -p xxxxxx

      - uses: actions/checkout@v1
      - name: Build the Docker image
        run: docker build . -t realtimechat-snapshot-0.$GITHUB_REF


      - uses: actions/checkout@v1
      - name: Tag the image
        run: docker tag realtimechat-snapshot-0.$GITHUB_REF realtimechat-snapshot-0



      - uses: actions/checkout@v1
      - name: Push the image
        run: docker push realtimechat-snapshot-0.$GITHUB_REF

在 Build the Docker image 步骤构建这个 Dockerfile:

FROM alpine:latest
COPY ./build/libs/realtimeChattingSystem-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT exec java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar

当它尝试复制 jar 文件时出现此错误：

COPY failed: stat /var/lib/docker/tmp/docker-builder207778036/build/libs/realtimeChattingSystem-0.0.1-SNAPSHOT.jar: no such file or directory

注意*

在 - run: ls ./build/libs/ 的步骤中，它实际上向我展示了 jar 文件：

Run ls ./build/libs/

realtimeChattingSystem-0.0.1-SNAPSHOT.jar

第 2 期

在此

中进行更改后

我遇到了另一个问题

这是步骤：

name: Java CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v1
      - name: Set up JDK 13
        uses: actions/setup-java@v1
        with:
          java-version: 13

      - run: ./gradlew bootJar

      - name: Login to Github regestry
        run: docker login docker.pkg.github.com -u xxxxx -p xxxxx

      - name: Build the Docker image
        run: docker build . -t docker.pkg.github.com/sulimanlab/realtime-chat/realtimechat-snapshot-0.$GITHUB_REF


      - name: Push the image to github
        run: docker push docker.pkg.github.com/sulimanlab/realtime-chat/realtimechat-snapshot-0.$GITHUB_REF

在最后步我得到这个错误：

The push refers to repository [docker.pkg.github.com/sulimanlab/realtime-chat/realtimechat-snapshot-0.refs/heads/master]

您只需在工作流程开始时使用 actions/checkout 一次。当您在构建后再次使用它时，我认为它可能会将您的本地工作区重置回 GITHUB_SHA 并且您的 jar 文件将在此过程中被删除。

试试这个：

name: Java CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - name: Set up JDK 11
        uses: actions/setup-java@v1
        with:
          java-version: 11

      - run: gradle wrapper

      - run: ./gradlew bootJar

      - run: ls ./build/libs/

      - name: Login to docker
        run: docker login docker.pkg.github.com -u xxxxxx -p xxxxxx

      - name: Build the Docker image
        run: docker build . -t realtimechat-snapshot-0.$GITHUB_REF

      - name: Tag the image
        run: docker tag realtimechat-snapshot-0.$GITHUB_REF realtimechat-snapshot-0

      - name: Push the image
        run: docker push realtimechat-snapshot-0.$GITHUB_REF
