# Alfresco Docker Base Java [](https://github.com/Alfresco/alfresco-docker-base-java/actions/workflows/main.yml) 
This repository provides the base Docker images for Java LTS versions
Rocky Linux 8 and 9 that are meant to be used within the Alfresco engineering to
build Docker images for Java applications.
## Flavours
Choose between one of the available flavours built from this repository:
Java version | Java flavour | OS | Image ref | Size
-------------|--------------|---------------|-------------------------------------------------|-----------------------------
17 | jre | Rocky Linux 8 | `alfresco/alfresco-base-java:jre17-rockylinux8` | ![jre17-rockylinux8 size][1]
11 | jre | Rocky Linux 8 | `alfresco/alfresco-base-java:jre11-rockylinux8` | ![jre11-rockylinux8 size][2]
17 | jre | Rocky Linux 9 | `alfresco/alfresco-base-java:jre17-rockylinux9` | ![jre17-rockylinux9 size][3]

[3]: https://img.shields.io/docker/image-size/alfresco/alfresco-base-java/jre17-rockylinux9
The images are available on:
* [Docker Hub](https://hub.docker.com/r/alfresco/alfresco-base-java), image name: `alfresco/alfresco-base-java`
* [Quay](https://quay.io/repository/alfresco/alfresco-base-java) (enterprise credentials required), image name: `quay.io/alfresco/alfresco-base-java`
### Image pinning
To ensure the propagation of security fixes from upstream projects, all
supported tags are mutable and undergo periodic rebuilding.
#### Pin by digest
The suggested approach is to pin the sha256 digest for best reproducibility in
your `Dockerfile`, for example:
```dockerfile
FROM alfresco/alfresco-base-java:jre17-rockylinux9@sha256:b749868ceb42bd6f58ae2f143e8c16af4752fad7b40eb1085c014cbfcecb1ffc
```
To discover the latest image digest, just run `docker pull ` and then
run `docker images --digests`.
```sh
$ docker pull alfresco/alfresco-base-java:jre17-rockylinux9
489e1be6ce56: Already exists
66defdfd2e26: Download complete
41c3b80bc03b: Download complete
be4e433e73b5: Download complete
docker.io/alfresco/alfresco-base-java:jre17-rockylinux9
$ docker images --digests
REPOSITORY TAG DIGEST IMAGE ID CREATED SIZE
alfresco/alfresco-base-java jre17-rockylinux9 sha256:b749868ceb42bd6f58ae2f143e8c16af4752fad7b40eb1085c014cbfcecb1ffc be4e433e73b5 14 minutes ago 410MB
```
This configuration approach is compatible with [Dependabot](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#docker).
#### Pin by immutable tags
Additional tags are being pushed for master releases, following the pattern
`$tag-YYMMDDHHMM`. Those tags are never overwritten and can be used as a more
intuitive approach. You can still use it in combination with digest for
increased security.
> Quay.io doesn't retain previous images when a tag is overwritten, so using an
> immutable tag is mandatory in order to avoid getting `Manifest not found`
> error once a mutable tag get updated.
## Development
While any docker installation will produce valid images, building with
[BuildKit](https://docs.docker.com/develop/develop-images/build_enhancements/)
has proven being more efficient and clever with [Multistage
builds](https://docs.docker.com/develop/develop-images/multistage-build/). If
you are building images locally, we recommend enabling it.
### Naming specs
The images built from this repository are named as follow:
`-`
### Build an image locally
To build a local version of the base java image follow the instructions below:
```bash
docker build -t alfresco-base-java . \
--build-arg DISTRIB_NAME=$DISTRIB_NAME \
--build-arg DISTRIB_MAJOR=$DISTRIB_MAJOR \
--build-arg JAVA_MAJOR=$JAVA_MAJOR \
--build-arg JDIST=$JDIST \
--no-cache --target JAVA_BASE_IMAGE
```
### Release
New images are built automatically on each new commit on master and on a weekly schedule.
