Additionally it creates a standard database user named `my-user`, with the password `my-password`, who has access to a database named `my-database`. + +Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example, + +```bash +$ helm install --name my-release -f values.yaml stable/mysql +``` + +> **Tip**: You can use the default [values.yaml](values.yaml) + +## Persistence + +The [MySQL](https://hub.docker.com/_/mysql/) image stores the MySQL data and configurations at the `/var/lib/mysql` path of the container. + +By default a PersistentVolumeClaim is created and mounted into that directory. In order to disable this functionality +you can change the values.yaml to disable persistence and use an emptyDir instead. + +> *"An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever."* + +**Notice**: You may need to increase the value of `livenessProbe.initialDelaySeconds` when enabling persistence by using PersistentVolumeClaim from PersistentVolume with varying properties. Since its IO performance has impact on the database initialization performance. The default limit for database initialization is `60` seconds (`livenessProbe.initialDelaySeconds` + `livenessProbe.periodSeconds` * `livenessProbe.failureThreshold`). Once such initialization process takes more time than this limit, kubelet will restart the database container, which will interrupt database initialization then causing persisent data in an unusable state. + +## Custom MySQL configuration files + +The [MySQL](https://hub.docker.com/_/mysql/) image accepts custom configuration files at the path `/etc/mysql/conf.d`. If you want to use a customized MySQL configuration, you can create your alternative configuration files by passing the file contents on the `configurationFiles` attribute. Note that according to the MySQL documentation only files ending with `.cnf` are loaded. + +```yaml +configurationFiles: + mysql.cnf: |- + [mysqld] + skip-host-cache + skip-name-resolve + sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION + mysql_custom.cnf: |- + [mysqld] +``` + +## MySQL initialization files + +The [MySQL](https://hub.docker.com/_/mysql/) image accepts *.sh, *.sql and *.sql.gz files at the path `/docker-entrypoint-initdb.d`. +These files are being run exactly once for container initialization and ignored on following container restarts. +If you want to use initialization scripts, you can create initialization files by passing the file contents on the `initializationFiles` attribute. + + +```yaml +initializationFiles: + first-db.sql: |- + CREATE DATABASE IF NOT EXISTS first DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci; + second-db.sql: |- + CREATE DATABASE IF NOT EXISTS second DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci; +``` + +## SSL + +This chart supports configuring MySQL to use [encrypted connections](https://dev.mysql.com/doc/refman/5.7/en/encrypted-connections.html) with TLS/SSL certificates provided by the user. This is accomplished by storing the required Certificate Authority file, the server public key certificate, and the server private key as a Kubernetes secret. The SSL options for this chart support the following use cases: + +* Manage certificate secrets with helm +* Manage certificate secrets outside of helm + +## Manage certificate secrets with helm + +Include your certificate data in the `ssl.certificates` section. For example: + +``` +ssl: + enabled: false + secret: mysql-ssl-certs + certificates: + - name: mysql-ssl-certs + ca: |- + -----BEGIN CERTIFICATE----- + ... + -----END CERTIFICATE----- + cert: |- + -----BEGIN CERTIFICATE----- + ... + -----END CERTIFICATE----- + key: |- + -----BEGIN RSA PRIVATE KEY----- + ... + -----END RSA PRIVATE KEY----- +``` + +> **Note**: Make sure your certificate data has the correct formatting in the values file. + +## Manage certificate secrets outside of helm + +1. Ensure the certificate secret exist before installation of this chart. +2. Set the name of the certificate secret in `ssl.secret`. +3. Make sure there are no entries underneath `ssl.certificates`. + +To manually create the certificate secret from local files you can execute: +``` +kubectl create secret generic mysql-ssl-certs \ + --from-file=ca.pem=./ssl/certificate-authority.pem \ + --from-file=server-cert.pem=./ssl/server-public-key.pem \ + --from-file=server-key.pem=./ssl/server-private-key.pem +``` +> **Note**: `ca.pem`, `server-cert.pem`, and `server-key.pem` **must** be used as the key names in this generic secret. + +If you are using a certificate your configurationFiles must include the three ssl lines under [mysqld] + +``` +[mysqld] + ssl-ca=/ssl/ca.pem + ssl-cert=/ssl/server-cert.pem + ssl-key=/ssl/server-key.pem +``` diff --git a/k8s/helm-1mysql/templates/NOTES.txt b/k8s/helm-1mysql/templates/NOTES.txt new file mode 100644 index 00000000..864170c0 --- /dev/null +++ b/k8s/helm-1mysql/templates/NOTES.txt @@ -0,0 +1,48 @@ +MySQL can be accessed via port 3306 on the following DNS name from within your cluster: +{{ template "mysql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local + +{{- if .Values.mysqlx.port.enabled }} +Connection to the X protocol of MySQL can be done via 33060 on the following DNS name from within your cluster: +{{ template "mysql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local +{{- end }} + +{{- if .Values.existingSecret }} +If you have not already created the mysql password secret: + + kubectl create secret generic {{ .Values.existingSecret }} --namespace {{ .Release.Namespace }} --from-file=./mysql-root-password --from-file=./mysql-password +{{ else }} + +To get your root password run: + + MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mysql.fullname" . }} -o jsonpath="{.data.mysql-root-password}" | base64 --decode; echo) +{{- end }} + +To connect to your database: + +1.
