Camel-k : Kamelet config experimentations

https://camel.apache.org/camel-k/1.12.x/kamelets/kamelets-user.html#_configuration

These examples uses mariadb.

Mariadb installation:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm install my-mariadb bitnami/mariadb --version 11.5.6 -f mariadb/values.yaml

kubectl run my-mariadb-client --rm --tty -i --restart='Never' --image  docker.io/bitnami/mariadb:10.6.12-debian-11-r16 --namespace default --command -- bash
mysql -h my-mariadb.default.svc.cluster.local -uroot -p my_database

In mariadb:

CREATE TABLE Customers (
    CustomerID int,
    LastName varchar(255),
    FirstName varchar(255),
    Address varchar(255),
    City varchar(255)
);
INSERT INTO Customers VALUES (1, "LN", "FN", "AD", "CT");
CREATE TABLE Employees (
    EmployeesID int,
    LastName varchar(255),
    FirstName varchar(255),
    Address varchar(255),
    City varchar(255)
);
INSERT INTO Employees VALUES (2, "LN", "FN", "AD", "CT");

Kubernetes configmaps

# default configmap
kubectl create configmap myintegration --from-file=./myintegration.properties

kubernetes secrets

# default secret
kubectl create secret generic mariadb-source \
    --from-literal=password=root \
    --from-literal=username=root \
    --from-literal=serverName=my-mariadb \
    --from-literal=databaseName=my_database \
    --from-literal='query=SELECT count(*) FROM Customers'
kubectl label secret mariadb-source camel.apache.org/kamelet=mariadb-source

# custom secret containing all the parameters with a different the query
kubectl create secret generic mariadb-source.secretintegrationcustom \
    --from-literal=password=root \
    --from-literal=username=root \
    --from-literal=serverName=my-mariadb \
    --from-literal=databaseName=my_database \
    --from-literal='query=SELECT * FROM Employees'
kubectl label secret mariadb-source.secretintegrationcustom camel.apache.org/kamelet=mariadb-source camel.apache.org/kamelet.configuration=secretintegrationcustom


# custom secret containing only a different the query
kubectl create secret generic mariadb-source.pipecustom \
    --from-literal='query=SELECT * FROM Persons'
kubectl label secret mariadb-source.pipecustom camel.apache.org/kamelet=mariadb-source camel.apache.org/kamelet.configuration=pipecustom
