So i have dockerized spring boot application, i have docker file:

FROM openjdk:17
ADD target/KIII_Project_Final-0.0.1-SNAPSHOT.jar KIII_Project_Final-0.0.1-SNAPSHOT.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "KIII_Project_Final-0.0.1-SNAPSHOT.jar"]

And my github action is :

name: Build & Deploy

on:
  push:
    branches: [ master ]
  workflow_dispatch:

jobs:
  build_and_push:
    name: Build & Push to DockerHub
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Login to DockerHub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_PASSWORD }}

      - name: Docker Build and Push to DockerHub
        uses: docker/build-push-action@v3
        with:
          context: .
          push: true
          tags: markoblazhevski/kiii:latest

and i get this error : Error: buildx failed with: ERROR: failed to solve: failed to compute cache key: failed to walk /var/lib/docker/tmp/buildkit-mount183090869/target: lstat /var/lib/docker/tmp/buildkit-mount183090869/target: no such file or directory

my github repository looks like this: IMAGE LINK I need help guys

I tried changing the action but it seems somehow the target folder cant be found , and i cant upload it and i dont know what to do, do i need to add something to my application or do i need to build it ? I am new to this so please help.

CodePudding user response：

There can be two solutions:

1. After docker login you can build and push by simple docker command

   - name: Docker Build and Push to DockerHub
   
     run: |
   
       docker build -t markoblazhevski/kiii:latest .
   
       docker push markoblazhevski/kiii:latest
   

2. Other way is if you want to use this action then you need to setup buildx first before the build and push step. You can follow the documentation here.
