Since the FROM syntax in dockerfile doesnt support a github repo link.
There are few Dockerfiles in github repo.
How could I use github action to build them and push to docker-registry once per day?
you can use this example:
name: ci
on:
push:
branches:
- 'master'
jobs:
docker:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout#v2
-
name: Set up QEMU
uses: docker/setup-qemu-action#v1
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action#v1
-
name: Login to DockerHub
uses: docker/login-action#v1
with:
username: ${{ secrets.DOCKERHUB_USERNAME }}
password: ${{ secrets.DOCKERHUB_TOKEN }}
-
name: Build and push
uses: docker/build-push-action#v2
with:
context: .
push: true
tags: user/app:latest

I'm trying to setup scheduled container rebuilds on my latest release (git tag).
I'm already building containers on main branch and version tags, but i'd like to expand the version tags to be a scheduled rebuild to pickup base image security updates. I can't figure out how to do scheduled actions on only the latest tag.
Suggestions welcome. My example repository is github.com/ruckc/container-openldap. I reuse this same workflow frequently, and just trying to improve it to handle base image updates.
on:
push:
branches: ['main']
tags:
- 'v*'
env:

Hi I am trying to create an image of a simple project holded on github and push it to docker hub, but I do not achieve it.
this is my .yml file:
name: workflow 3
on: push
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout#v2
- name: Set up QEMU
uses: docker/setup-qemu-action#v1
- name: Set up Docker Buildx
uses: docker/setup-buildx-action#v1
- name: login to docker hub
uses: docker/login-action#v1
with:
username: ${{ secrets.DOCKER_NAME }}
password: ${{ secrets.DOCKER_TOKEN }}
- name: Build and push
uses: docker/build-push-action#v2
with:
context: .
push: true
tags: user/app:latest
but I receive this error: Error: buildx failed with: error: failed to solve: failed to read dockerfile: open /tmp/buildkit-mount2002185417/Dockerfile: no such file or directory
I have a simple pipeline in GitHub Actions. I'm trying to build and publish a Docker image to Docker Hub within the same. I would also like to build the image for different platforms (read: operating systems), hence I'm using strategy.matrix. This is how it looks like so far:
name: Build and Publish Docker image(s)
jobs:
publish:
runs-on: ubuntu-latest
steps:
- name: Check out repository
uses: actions/checkout#v2
- name: Log in to Docker Hub
uses: docker/login-action#v1
with:
password: ${{ secrets.DOCKERHUB_TOKEN }}
registry: docker.io
username: ${{ secrets.DOCKERHUB_USERNAME }}
- name: Build and push
uses: docker/build-push-action#v2
env:
platform: ${{ matrix.platforms }}
with:
context: ./${platform}/
push: true
tags: oscarotero/lume:1.3.0-${platform} # TODO: Parameterize version once this is finally working
strategy:
matrix:
platforms:
- alpine
- debian
on:
push:
branches:
- main
This is currently failing because it doesn't recognize platform when running the Build and push step. I have a similar one and it works with this approach.
Anyone more knowledgeable in GitHub Actions can shred some light here? All I can think of is that docker/build-push-action#v2 doesn't support that, but in that case, how can I approach this problem?
Removing the environment variable and using the matrix values directly solved the problem:
jobs:
publish:
runs-on: ubuntu-latest
steps:
- name: Check out repository
uses: actions/checkout#v2
- name: Log in to Docker Hub
uses: docker/login-action#v1
with:
password: ${{ secrets.DOCKERHUB_TOKEN }}
registry: docker.io
username: ${{ secrets.DOCKERHUB_USERNAME }}
- name: Build and push
uses: docker/build-push-action#v2
with:
context: ./${{ matrix.platform }}/
push: true
tags: oscarotero/lume:1.3.0-${{ matrix.platform }}
strategy:
matrix:
platform:
- alpine
- debian
I want to build my image and push it to dockerhub using github actions.This is my repo
And this is how I want to do my job:
name: ci
on:
push:
branches:
- 'master'
jobs:
docker:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout#v2
-
name: Set up QEMU
uses: docker/setup-qemu-action#v1
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action#v1
-
name: Login to DockerHub
uses: docker/login-action#v1
with:
username: ${{ secrets.DOCKERHUB_USERNAME }}
password: ${{ secrets.DOCKERHUB_PASSWORD }}
-
name: Build and push
uses: docker/build-push-action#v2
with:
context: .
load: true
tags: shirzadi/ehsan:latest
-
name: Push it!
run: docker push ${{ env.IMAGE }}:${{ env.GIT_SHA }}
And this is the result:
You are using environment variables that don't exist. According to docker/build-push-action#v2 documentation it can build, tag and push your image in a single step:
jobs:
docker:
steps:
# ...
-
name: Build and push
uses: docker/build-push-action#v2
with:
context: .
push: true
tags: shirzadi/ehsan:latest,shirzadi/ehsan:${{ env.GITHUB_SHA }}
The tags key lists 2 tags and use the GITHUB_SHA environment variable. These tags will be pushed as the push key is set to true.
See:
Github Actions - Default environment variables
docker/build-push-action#v2 - customizing inputs
You are not having env.IMAGE data. Below piece of code should do the job.
- name: Build and push
run: docker build -t ${{ env.IMAGE }}:${{ github.sha }} .
env:
IMAGE: shirzadi/ehsan
- name: Push it!
run: docker push ${{ env.IMAGE }}:${{ github.sha }}
env:
IMAGE: shirzadi/ehsan
I'm trying to deploy my repository to a private Docker registry on every new release and everything works except for the version tagging. No matter what I've tried ${{ github.event.release.tag_name }} is always '', which cancels the workflow since docker tags can't be empty.
on:
release:
types: [published]
jobs:
push_to_registry:
name: Push Docker image to Docker Registry
runs-on: ubuntu-latest
steps:
-
name: Check out the repo
uses: actions/checkout#v2
-
name: Set up QEMU
uses: docker/setup-qemu-action#v1
-
name: Setup Docker Buildx
uses: docker/setup-buildx-action#v1
-
name: Log in to Docker Registry
uses: docker/login-action#v1
with:
registry: ${{ secrets.DOCKER_REGISTRY }}
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
- name: check tag
if: ${{ github.event.release.tag_name }} == ''
run: |
echo Epic fail
exit 1
-
name: Build and Push to Docker Registry
id: docker_build
uses: docker/build-push-action#v2
with:
push: true
tags: ${{ secrets.DOCKER_REGISTRY }}/repos:latest, ${{ secrets.DOCKER_REGISTRY }}/$repos:${{ github.event.release.tag_name }}
-
name: Image digest
run: echo ${{ steps.docker_build.outputs.digest }}
The repository this is running on is private so that might have something to do with it but I haven't been able to figure out what.
Any suggestions?
I think the problem is that github.event.release.tag_name is only available if the tagging itself triggered the build (but I'm not sure)
I made it work using a separate action: https://github.com/dawidd6/action-get-tag
Here's my usage:
steps:
- uses: actions/checkout#v2
- name: Get git tag
id: tag
uses: dawidd6/action-get-tag#v1
- uses: docker/build-push-action#v2
with:
context: ./
file: ./Dockerfile
push: true
tags: locustio/locust:${{ steps.tag.outputs.tag }}
