+# Scheduling inside a docker container
+
+[Discussion](https://github.com/creativeprojects/resticprofile/issues/74)
+
+You can schedule your backups with resticprofile by running `crond` inside a container.
+
+Here's a `docker-compose` example:
+
+```yaml
+version: '2'
+
+services:
+  scheduled-backup:
+    image: creativeprojects/resticprofile:${RP_VERSION:-latest}
+    container_name: backup_container
+    hostname: backup_container
+    entrypoint: '/bin/sh'
+    command:
+      - '-c'
+      - 'resticprofile schedule --all && crond -f'
+    volumes:
+      - ~/.ssh:/root/.ssh
+      - './profiles.yaml:/etc/resticprofile/profiles.yaml:ro'
+      - './key:/etc/resticprofile/key:ro'
+    environment:
+      - TZ=Etc/UTC
+```
+
+with the corresponding resticprofile configuration running a backup every 15 minutes:
+
+```yaml
+
+global:
+  scheduler: crond
+
+default:
+  password-file: key
+  repository: sftp:storage_server:/tmp/backup
+  initialize: true
+  backup:
+    source: /
+    exclude-caches: true
+    one-file-system: true
+    schedule: "*:00,15,30,45"
+    schedule-permission: system
+    check-before: true
+
+```
