Usage

docker run -d [OPTIONS] istepanov/backup-to-s3

Parameters:

• -e ACCESS_KEY=<AWS_KEY>: Your AWS key.
• -e SECRET_KEY=<AWS_SECRET>: Your AWS secret.
• -e S3_PATH=s3://<BUCKET_NAME>/<PATH>/: S3 Bucket name and path. Should end with trailing slash.

• no-cron: run container once and exit (no cron scheduling).

Examples:

Run upload to S3 everyday at 12:00pm:

docker run -d \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    -e 'CRON_SCHEDULE=0 12 * * *' \
    -v /home/user/data:/data:ro \
    istepanov/backup-to-s3

Run once then delete the container:

docker run --rm \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    -v /home/user/data:/data:ro \
    istepanov/backup-to-s3 no-cron

Run once to get from S3 then delete the container:

docker run --rm \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    -v /home/user/data:/data:rw \
    istepanov/backup-to-s3 get

Run once to delete from s3 then delete the container:

docker run --rm \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    istepanov/backup-to-s3 delete

Security considerations: on restore, this opens up permissions on the restored files widely.
