stable/mysqldump/README.md
CHART WAS DEPRECATED AND MOVED TO https://github.com/kokuwaio/helm-charts/tree/main/charts/mysqldump
mysqldump is a tool for creating backups of MySQL databases in the form of a .sql file.
helm install stable/mysqldump \
--set mysql.host=mysql;mysql.username=root,mysql.password=password,persistence.enabled=true
This chart helps set up a cronjob or one time job to backup a MySQL database with mysqldump into a Persistent Volume. You can specify an existing PVC, or helm will create one for you.
To install the chart with the release name my-release:
helm install stable/mysqldump \
--set mysql.host=mysql,mysql.username=root,mysql.password=password,persistence.enabled=true
This command will create a cronjob to run a job once a day to backup the databases found on the host mysql
Tip: List all releases using
helm list
To uninstall/delete the my-release deployment:
helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.

By enabling the flag upload.googlestoragebucket.usingGCPController and having a GCP Service Account Controller deployed in your cluster, it is possible to autogenerate and inject the service account used for the storage bucket access.

helm install stable/mysqldump --name my-release \
--set persistentVolumeClaim=name-of-existing-pvc
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
helm install stable/mysqldump --name my-release -f values.yaml
