# Share built image between jobs
As each job is isolated in its own runner you cannot use your built image between jobs (except for [self-hosted runners](https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners)).
However, you can [pass data between jobs in a workflow](https://docs.github.com/en/actions/guides/storing-workflow-data-as-artifacts#passing-data-between-jobs-in-a-workflow)
using the [actions/upload-artifact](https://github.com/actions/upload-artifact) and [actions/download-artifact](https://github.com/actions/download-artifact)
actions:
```yaml
name: ci
on:
push:
branches:
- 'master'
jobs:
build:
runs-on: ubuntu-latest
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action@v1
-
name: Build and export
uses: docker/build-push-action@v2
with:
context: .
tags: myimage:latest
outputs: type=docker,dest=/tmp/myimage.tar
-
name: Upload artifact
uses: actions/upload-artifact@v2
with:
name: myimage
path: /tmp/myimage.tar
use:
runs-on: ubuntu-latest
needs: build
steps:
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action@v1
-
name: Download artifact
uses: actions/download-artifact@v2
with:
name: myimage
path: /tmp
-
name: Load image
run: |
docker load --input /tmp/myimage.tar
docker image ls -a
```
