Docker image to backup your Docker container volumes. Why the name? Docker + Backup = Dockup!
Using /config/env.sh file that outputs required env vars, backups up the target folder to S3 on demand or via cron schedule. The contents of env.sh being:
#!/bin/bash
export AWS_ACCESS_KEY_ID=[ACCESS_KEY] # AWS Access Key
export AWS_SECRET_ACCESS_KEY=[ACCESS_KEY_SECRET] # AWS Secret Access Key
export AWS_DEFAULT_REGION=us-east-1 # AWS Region
export BACKUP_NAME=[BACKUP_FILE_NAME] # What to call the backup file in S3
export PATHS_TO_BACKUP=/backup # Path mapped in container to backup
export S3_BUCKET_NAME=[S3_BUCKET_NAME] # Bucket name to back up to
export RESTORE=false # Run in restore mode (restore s3 backup file to backup path)
export CRON_TIME=0\ 2\ *\ *\ * # every night at 2am (omit for on demand)
dockup will use your AWS credentials to create a new bucket with name as per the environment variable S3_BUCKET_NAME, or if not defined. The paths in PATHS_TO_BACKUP will be tarballed, gzipped, time-stamped and uploaded to the S3 bucket.
/backup - mount the folder to be backed up here
/config/env.sh - environment variables to control backups
LOGSPOUT:ignore - [optional] tell Logspout to ignore these logs
To restore your data simply set the RESTORE environment variable to true - this will restore the latest backup from S3 to your volume.
