|
||||
|
||||
## Configuration
|
||||
|
||||
Per default Backupbot stores the backups locally in the repository `/backups/restic`, which is accessible as volume at `/var/lib/docker/volumes/<backupbot_name>_backups/_data/restic/`
|
||||
|
||||
The backup location can be changed using the `RESTIC_REPOSITORY` env variable.
|
||||
|
||||
### S3 Storage
|
||||
|
||||
To use S3 storage as backup location set the following envs:
|
||||
```
|
||||
RESTIC_REPOSITORY=s3:<S3-SERVICE-URL>/<BUCKET-NAME>
|
||||
SECRET_AWS_SECRET_ACCESS_KEY_VERSION=v1
|
||||
AWS_ACCESS_KEY_ID=<MY_ACCESS_KEY>
|
||||
COMPOSE_FILE="$COMPOSE_FILE:compose.s3.yml"
|
||||
```
|
||||
and add your `<SECRET_ACCESS_KEY>` as docker secret:
|
||||
`abra app secret insert <backupbot_name> aws_secret_access_key v1 <SECRET_ACCESS_KEY>`
|
||||
|
||||
See [restic s3 docs](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#amazon-s3) for more information.
|
||||
|
||||
### SFTP Storage
|
||||
|
||||
> With sftp it is not possible to prevent the backupbot from deleting backups in case of a compromised machine. Therefore we recommend to use S3, REST or rclone server without delete permissions.
|
||||
|
||||
To use SFTP storage as backup location set the following envs:
|
||||
```
|
||||
RESTIC_REPOSITORY=sftp:user@host:/restic-repo-path
|
||||
SECRET_SSH_KEY_VERSION=v1
|
||||
SSH_HOST_KEY="hostname ssh-rsa AAAAB3...
|
||||
COMPOSE_FILE="$COMPOSE_FILE:compose.ssh.yml"
|
||||
```
|
||||
To get the `SSH_HOST_KEY` run the following command `ssh-keyscan <hostname>`
|
||||
|
||||
Generate an ssh keypair: `ssh-keygen -t ed25519 -f backupkey -P ''`
|
||||
Add the key to your `authorized_keys`:
|
||||
`ssh-copy-id -i backupkey <user>@<hostname>`
|
||||
Add your `SSH_KEY` as docker secret:
|
||||
```
|
||||
abra app secret insert <backupbot_name> ssh_key v1 """$(cat backupkey)
|
||||
"""
|
||||
```
|
||||
> Attention: This command needs to be executed exactly as stated above, because it places a trailing newline at the end, if this is missing you will get the following error: `Load key "/run/secrets/ssh_key": error in libcrypto`
|
||||
|
||||
### Restic REST server Storage
|
||||
|
||||
You can simply set the `RESTIC_REPOSITORY` variable to your REST server URL `rest:http://host:8000/`.
|
||||
If you access the REST server with a password `rest:https://user:pass@host:8000/` you should hide the whole URL containing the password inside a secret.
|
||||
Uncomment these lines:
|
||||
```
|
||||
SECRET_RESTIC_REPO_VERSION=v1
|
||||
COMPOSE_FILE="$COMPOSE_FILE:compose.secret.yml"
|
||||
```
|
||||
Add your REST server url as secret:
|
||||
```
|
||||
abra app secret insert <backupbot_name> restic_repo v1 "rest:https://user:pass@host:8000/"
|
||||
```
|
||||
The secret will overwrite the `RESTIC_REPOSITORY` variable.
|
||||
|
||||
|
||||
See [restic REST docs](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server) for more information.
|
||||
|
||||
## Push notifications
|
||||
|
||||
The following env variables can be used to setup push notifications for backups. `PUSH_URL_START` is requested just before the backups starts, `PUSH_URL_SUCCESS` is only requested if the backup was successful and if the backup fails `PUSH_URL_FAIL` will be requested.
|
||||
Each variable is optional and independent of the other.
|
||||
```
|
||||
|
||||
PUSH_URL_START=https://status.example.com/api/push/xxxxxxxxxx?status=up&msg=start
|
||||
PUSH_URL_SUCCESS=https://status.example.com/api/push/xxxxxxxxxx?status=up&msg=OK
|
||||
PUSH_URL_FAIL=https://status.example.com/api/push/xxxxxxxxxx?status=down&msg=fail
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
Run the cronjob that creates a backup, including the push notifications and docker logging:
|
||||
`abra app cmd <backupbot_name> app run_cron`
|
||||
|
||||
Create a backup of all apps:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup create`
|
||||
|
||||
> The apps to backup up need to be deployed
|
||||
|
||||
Create an individual backup:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup --host <target_app_name> create`
|
||||
|
||||
Create a backup to a local repository:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup create -r /backups/restic`
|
||||
|
||||
> It is recommended to shutdown/undeploy an app before restoring the data
|
||||
|
||||
Restore the latest snapshot of all including apps:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup restore`
|
||||
|
||||
Restore a specific snapshot of an individual app:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup --host <target_app_name> restore --snapshot <snapshot_id>`
|
||||
|
||||
Show all snapshots:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup snapshots`
|
||||
|
||||
Show all snapshots containing a specific app:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup --host <target_app_name> snapshots`
|
||||
|
||||
Show all files inside the latest snapshot (can be very verbose):
|
||||
|
||||
`abra app run <backupbot_name> app -- backup ls`
|
||||
|
||||
Show specific files inside a selected snapshot:
|
||||
|
||||
`abra app run <backupbot_name> app -- backup ls --snapshot <snapshot_id> --path /var/lib/docker/volumes/`
|
||||
|
||||
Download files from a snapshot:
|
||||
|
||||
```
|
||||
filename=$(abra app run <backupbot_name> app -- backup download --snapshot <snapshot_id> --path <absolute_path>)
|
||||
abra app cp <backupbot_name> app:$filename .
|
||||
```
|
||||
|
||||
## Run restic
|
||||
|
||||
```
|
||||
abra app run <backupbot_name> app bash
|
||||
export AWS_SECRET_ACCESS_KEY=$(cat $AWS_SECRET_ACCESS_KEY_FILE)
|
||||
export RESTIC_PASSWORD=$(cat $RESTIC_PASSWORD_FILE)
|
||||
restic snapshots
|
||||
```
|
||||
|
||||
## Recipe Configuration
|
||||
|
||||
Like Traefik, or `swarm-cronjob`, Backupbot II uses access to the Docker socket to read labels from running Docker Swarm services:
|
||||

|

As in the above example, you can reference Docker Secrets, e.g. for looking up database passwords, by reading the files in `/run/secrets` directly.
|
||||
|
||||
## Development
|
||||
|
||||
1. Install `direnv`
|
||||
2. `cp .envrc.sample .envrc`
|
||||
3. Edit `.envrc` as appropriate, including setting `DOCKER_CONTEXT` to a remote Docker context, if you're not running a swarm server locally.
|
||||
4. Run `./backup.sh` -- you can add the `--skip-backup` or `--skip-upload` options if you just want to test one other step
|
||||
|
||||
[abra]: https://git.autonomic.zone/autonomic-cooperative/abra
|
||||
|
||||
## Backupbot Development
|
||||
|
||||
1. Copy modified backupbot.py into the container:
|
||||
|
||||
```
|
||||
cp backupbot.py /tmp/backupbot.py; git stash; abra app cp <backupbot_name> /tmp/backupbot.py app:/usr/bin/backupbot.py; git checkout main; git stash pop
|
||||
```
|
||||
|
||||
2. Testing stuff with the python interpreter inside the container:
|
||||
|
||||
```
|
||||
abra app run <backupbot_name> app bash
|
||||
cd /usr/bin/
|
||||
python
|
||||
from backupbot import *
|
||||
```
|
||||
|
||||
### Versioning
|
||||
|
||||
- App version: changes to `backup.py` (build a new image)
|
||||
- Co-op Cloud package version: changes to recipe.
|
||||
|
||||
For example, starting with 1.0.0+2.0.0:
|
||||
"patch" change to recipe: 1.0.1+2.0.0
|
||||
"patch" change to backup.py: increment both, so 1.1.0+2.0.1
|
||||
because bumping the image version would result in a minor recipe release
