+# Overview
+
+mysql for Kubernetes
+
+# Usage
+
+You must specify key configuration attributes when deploying,
+or else arbitary defaults will be used. The attributes which
+should be set are:
+- user
+- password
+- database
+- root_password
+
+eg
+
+$ juju deploy mysql \
+&nbsp;&nbsp;&nbsp;&nbsp;--config user=fred \
+&nbsp;&nbsp;&nbsp;&nbsp;--config password=secret \
+&nbsp;&nbsp;&nbsp;&nbsp;--config database=test \
+&nbsp;&nbsp;&nbsp;&nbsp;--config root_password=admin
+
+These values may also be in a config.yaml file, eg
+
+$ juju deploy mysql --config config.yaml
+
+
+## Actions
+
+### Backup
+
+Execute the following steps to do a backup.
+
+```bash
+$ juju run-action mariadb-k8s/0 backup --wait
+unit-mariadb-k8s-0:
+  UnitId: mariadb-k8s/0
+  id: "1"
+  results:
+    copy:
+      cmd: kubectl cp zaza-9769f2bf245e/mariadb-k8s-0:/var/lib/mysql/backup.sql.gz
+        backup.sql.gz
+    restore:
+      cmd: kubectl cp backup.sql.gz zaza-9769f2bf245e/mariadb-k8s-0:/var/lib/mysql/backup.sql.gz
+      juju: juju run-action mariadb-k8s/0 restore --wait
+  status: completed
+  timing:
+    completed: 2020-02-27 14:16:09 +0000 UTC
+    enqueued: 2020-02-27 14:16:08 +0000 UTC
+    started: 2020-02-27 14:16:09 +0000 UTC
+$ kubectl cp zaza-9769f2bf245e/mariadb-k8s-0:/var/lib/mysql/backup.sql.gz backup.sql.gz
+```
+
+> Additional note: You can add `--string-args target=PRIMARY|SECONDARY` if you want this action to be run in a specific mongo unit. If `SECONDARY` is set, but the mongo unit isn't the `SECONDARY`, the action will fail.
+
+### Restore
+
+When the backup function is executed, you will see the commands you need to execute for restoring from a backup.
+
+```bash
+$ kubectl cp backup.sql.gz zaza-9769f2bf245e/mariadb-k8s-0:/var/lib/mysql/backup.sql.gz
+$ juju run-action mariadb-k8s/0 restore --wait
+unit-mariadb-k8s-0:
+  UnitId: mariadb-k8s/0
+  id: "2"
+  results:
+    message: Backup restored successfully
+  status: completed
+  timing:
+    completed: 2020-02-27 14:18:17 +0000 UTC
+    enqueued: 2020-02-27 14:18:07 +0000 UTC
+    started: 2020-02-27 14:18:11 +0000 UTC
+```
+
+### Remove backup
+
+When a backup is made, it is stored in the unit. To easily remove the backup, execute this action:
+
+```bash
+$ juju run-action mariadb-k8s/0 remove-backup --wait
+unit-mariadb-k8s-0:
+  UnitId: mariadb-k8s/0
+  id: "3"
+  results:
+    Stdout: |
+      Backup successfully removed!
+  status: completed
+  timing:
+    completed: 2020-02-27 14:18:41 +0000 UTC
+    enqueued: 2020-02-27 14:18:36 +0000 UTC
+    started: 2020-02-27 14:18:41 +0000 UTC
+```
+
+## Backup remotely
+
+If we want to perform a backup remotely, follow the next steps:
+
+```bash
+$ sudo apt install mariadb-client-10.1 -y
+$ juju status mariadb-k8s
+Model              Controller          Cloud/Region        Version  SLA          Timestamp
+zaza-9769f2bf245e  microk8s-localhost  microk8s/localhost  2.7.2    unsupported  15:20:42+01:00
+
+App            Version             Status  Scale  Charm        Store  Rev  OS          Address         Notes
+mariadb-k8s    rocks.canonical...  active  2      mariadb-k8s  local  0    kubernetes  10.152.183.109  
+
+Unit            Workload  Agent  Address      Ports                                Message
+mariadb-k8s/0*  active    idle   10.1.31.185  3306/TCP,4444/TCP,4567/TCP,4568/TCP  ready
+mariadb-k8s/1   active    idle   10.1.31.186  3306/TCP,4444/TCP,4567/TCP,4568/TCP  ready
+$ mysqldump -uroot -posm4u --single-transaction \
+                           --databases database \
+                           --host 10.152.183.109 \
+                           --port 3306 | gzip > backup.sql.gz
+$ gunzip -c backup.sql.gz | mysql -uroot -posm4u --host 10.152.183.109 --port 3306
+```
+
+> Note: The remote backups should be done for each database. If `--all-databases` is step, when restoring from a database, you will see this error: `ERROR 1556 (HY000) at line 825: You can't use locks with log tables`
+
+## Testing
+
+The tests of this charm are done using tox and Zaza.
+
+### Prepare environment
+
+The machine in which the tests are run needs access to a juju k8s controller. The easiest way to approach this is by executing the following commands:
+
+```bash
+sudo apt install tox -y
+sudo snap install microk8s --classic
+sudo snap install juju
+
+microk8s.status --wait-ready
+microk8s.enable storage dns
+
+juju bootstrap microk8s k8s-cloud
+```
+
+### Test charm with Tox
+
+```bash
+tox -e black    # Check syntax
+tox -e build    # Build the charm
+tox -e func     # Test charm
+```
