dbaas-operator

DBaaS Operator

This operator is meant to be used as a replacement for the ansible service broker and https://github.com/amazeeio/dbaas-mariadb-apb to run in Kubernetes.

Components

• MariaDBProvider - These contain the core connection details for a specific provider (AWS RDS, Azure DB for MySQL, etc)
• MariaDBConsumer - These contain the specific connection details for a consumer, multiple consumers can be defined in the one namespace and each will get their own specific service endpoints created pointing to the provider.

Developing

Install Kubebuilder

os=$(go env GOOS)
arch=$(go env GOARCH)

# download kubebuilder and extract it to tmp
curl -L https://go.kubebuilder.io/dl/2.2.0/${os}/${arch} | tar -xz -C /tmp/

# move to a long-term location and put it on your path
# (you'll need to set the KUBEBUILDER_ASSETS env var if you put it somewhere else)
sudo mv /tmp/kubebuilder_2.2.0_${os}_${arch} /usr/local/kubebuilder
export PATH=$PATH:/usr/local/kubebuilder/bin

Test It Out

This will spin up a local mysql provider, and then start kind and installs the operator and runs some basic tests to confirm the operation of the operator

Using circleci locally

circleci build -v $(pwd):/workdir

make operator-test

# if at anypoint you need to clean up
make clean
