create the helm chart with help pf create command of helm

helm create relayr

add mysql dependency to the Chart.yml file dependencies:

  • name: mysql version: chart version repository: repo condition: enable condition

add the dependency details in the vaules.yaml file as well

creating secrets

for creating secrets create a helm_vars directory

add you data to be stored as encrypted

in our case database details are stored

  1. database password : MYSQLDB_PASSWORD
  2. database : MYSQL_DATABASE
  3. database user : MYSQLDB_USER
  4. database root_password : MYSQL_ROOT_PASSWORD

create the data basesetails save it secrets file in followoing format

mariadb: auth: database: password: username: rootPassword:

once saved generate the pgp key. [which should be installed plugin to be installed ]

add a new file to the helm_vars file named .sops.yaml

  1. create gpg key gpg --gen-key

  2. gpg --fingerprint to get the finger print

  3. add the this valuie to .sops.yanl file

    creation_rules:

    • pgp: 'add the value to the gpg key'

  4. encrypt the value in secrets.yaml helm secrets enc ./helm_vars/secrets.yaml

  5. you can decrypt and check value helm secrets dec ./helm_vars/secrets.yaml cat value in secrets.yaml.dec

Running the appplication

  1. check dependencies helm repo update helm dep update

  2. encrypt the secrets

  3. check the encrypted values

  4. run in debug --dry run mode to check the whole structure helm secrets install appname . -f ./helm_vars/secrets.yaml -f values.yaml --dry-run --debug appname= relayr

Creating presistant volume

  1. create mysql persistant volume for making the database persistant kubectl apply -f pvcmysql.yaml [file is located outside the helm charts repo]

Accesing the application

  1. run minikube

  2. access the with http://minikubeip:nodeport

  3. create table for database [table name alredy given as hello ] http://minikubeip:nodeport/create_table

  4. access http://minikubeip:nodeport/login to add the string to the database table

  5. access the data from database with http://minikubeip:nodeport/temp
