This is a fork of https://github.com/travelaudience/docker-nexus-backup edited very minimally to use AWS s3 instead of google cloud storage. And by minimally i mean like %s/gsutil/aws s3/g.

It is hastily designed as a drop-in replacement for the backup mechanism of the helm chart for Nexus.

A container image for backing-up Sonatype Nexus Repository Manager data into S3 Cloud Storage.

Nexus Repository Manager can be configured to back-up its internal database on a regular basis. However, this process does not take blob stores into account. Furthermore, the back-ups are persisted in the local disk alone, meaning if the disk is lost, the back-ups are lost too.

This tool addresses these two shortcomings by backing-up the default blob store and then uploading everything to S3, including the database back-up Nexus previously created. This procedure is automatically triggered by touchinging ${NEXUS_BACKUP_DIRECTORY}/.backup.

When the back-up starts, a lock file is created so that no two backup processes run simultaneously. This lock file is removed automatically after a successful backup. A warning message is displayed whenever a lock file has been present for more than twelve hours (meaning a failed backup), and the lock file is removed so that further back-ups can be made.

Starting from version 1.4.0, docker-nexus-backup is only compatible with Nexus 3.8.0 and above. Users requiring support for earlier versions of Nexus must use version 1.3.0.

The simplest way to run the container is to assume the default configuration (check below for the default configuration):

docker run --detach                                               \
           --name nexus-backup                                    \
           --volume /path/to/nexus-data:/nexus-data               \
           --volume /path/to/nexus-data-backup:/nexus-data/backup \
           quay.io/travelaudience/docker-nexus-backup:1.4.0

You can change, for example, the repositories which to lock during backup and the target Google Cloud Storage bucket by specifing the correct values as environment variables:

docker run --detach \
           --env OFFLINE_REPOS="docker-hosted maven-central maven-public maven-releases maven-snapshots" \
           --env TARGET_BUCKET="s3://my-fancy-bucket/" \
           --name nexus-backup \
           --volume /path/to/nexus-data:/nexus-data \
           --volume /path/to/nexus-data-backup:/nexus-data/backup \
           quay.io/travelaudience/docker-nexus-backup:1.4.0

Use IAM. I use kube2iam, but I'm not the boss of you.

This image can be configured by means of environment variables. You will most probably want to customize NEXUS_AUTHORIZATION, NEXUS_LOCAL_HOST_PORT and TARGET_BUCKET to suit your use case, while most other environment variables will require no changes.
