Cockroach DB deployment

Step 1. Create a bridge network

$ docker network create -d bridge roachnet

Step 2. Start the cluster

1. Create a Docker volume for each container:

$ docker volume create roach1
$ docker volume create roach2
$ docker volume create roach3

2. Start the first node:

$ docker run -d \
--name=roach1 \
--hostname=roach1 \
--net=roachnet \
-p 26257:26257 -p 8080:8080  \
-v "roach1:/cockroach/cockroach-data"  \
cockroachdb/cockroach:v22.1.6 start \
--insecure \
--join=roach1,roach2,roach3

3. Start two more nodes:

$ docker run -d \
--name=roach2 \
--hostname=roach2 \
--net=roachnet \
-v "roach2:/cockroach/cockroach-data" \
cockroachdb/cockroach:v22.1.6 start \
--insecure \
--join=roach1,roach2,roach3

$ docker run -d \
--name=roach3 \
--hostname=roach3 \
--net=roachnet \
-v "roach3:/cockroach/cockroach-data" \
cockroachdb/cockroach:v22.1.6 start \
--insecure \
--join=roach1,roach2,roach3

$ docker exec -it roach1 ./cockroach init --insecure
