My CockroachDB Go example.
This can be tested in docker compose or in a kind kubernetes cluster.
List this repository dependencies (and which have newer versions):
GITHUB_COM_TOKEN='YOUR_GITHUB_PERSONAL_TOKEN' ./renovate.sh
Install docker and docker compose.
Create the environment:
docker compose up --build --detach
docker compose ps
docker compose logs
Start the cockroachdb client:
docker compose exec cockroachdb cockroach sql --no-line-editor --insecure
Execute some commands:
-- show information the postgresql version.
select version();
-- list roles.
\dg
-- list databases.
\l
-- insert a quote.
insert into quote(id, author, text, url) values(100, 'Hamlet', 'To be, or not to be, that is the question.', null);
-- select all quotes.
select text || ' -- ' || author as quote from quote;
-- exit
\q
Get a quote from the service:
wget -qO- http://localhost:4000
Destroy the environment:
docker compose down --volumes --remove-orphans --timeout=0
Install docker, kind, kubectl, and helm.
Create the local test infrastructure:
./.github/workflows/kind/create.sh
Access the test infrastructure kind Kubernetes cluster:
export KUBECONFIG="$PWD/kubeconfig.yml"
kubectl get nodes -o wide
Start the cockroachdb client:
kubectl exec --quiet --stdin --tty statefulset/cockroachdb -- \
cockroach sql \
--certs-dir /cockroach/cockroach-certs \
--no-line-editor
Execute some commands:
-- show information the postgresql version.
select version();
-- list roles.
\dg
-- list databases.
\l
-- insert a quote.
insert into quote(id, author, text, url) values(100, 'Hamlet', 'To be, or not to be, that is the question.', null);
-- select all quotes.
select text || ' -- ' || author as quote from quote;
-- exit
\q
Build and use the use-cockroachdb-go example:
./build.sh && ./deploy.sh && ./test.sh && xdg-open index.html
Destroy the local test infrastructure:
./.github/workflows/kind/destroy.sh
