CockroachDB it’s a distributed relational database, it’s written in Go language
It’s cross-platform (Runs on Windows, Mac and Linux)
Brings the best of both Databases worlds
- Scale
- Consistency
- Resiliency
- SQL (ACID guaranteed)
Uses PostgreSQL wire protocol
PostgreSQL Compatibility

First we need to build the charm
charmcraft pack
Spin up a three units cluster
juju deploy -n 3 ./cockroachdb-operator.charm --resource cockroachdb-image=cockroachdb/cockroach:v21.1.1
juju run-action cockroachdb-operator/leader init --wait
We can use any cluster node IP address and access it via following URL
http://\<Any Cockroach Cluster Node IP Address\>:8080
Or we can use nginx-ingress-integrator
juju deploy nginx-ingress-integrator
juju relate cockroachdb-operator nginx-ingress-integrator
Change ingress class to public
juju config nginx-ingress-integrator ingress-class="public"
Add cockroachdb.juju entry in your /etc/hosts
echo "127.0.1.1 cockroachdb.juju" | sudo tee -a /etc/hosts
Create and activate a virtualenv with the development requirements:
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements-dev.txt
The Python operator framework includes a very nice harness for testing
operator behaviour without full deployment. Just run_tests:
./run_tests
