- Some knowledge of Spring boot and docker will be helpful.
Here, I am using docker for ease of set up
Run below command to run vault server in development mode
docker run --cap-add=IPC_LOCK -d --name=dev-vault -p8200:8200 -e 'VAULT_DEV_ROOT_TOKEN_ID=myroot' vault
Confirm that docker is up using below command
ritgirdh$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9ad13a11b2d5 vault "docker-entrypoint.s…" 25 hours ago Up 25 hours 0.0.0.0:8200->8200/tcp dev-vault
Login http://localhost:8200/ui/ with token value myroot // TODO - screen shot
Now create secret for weather service
docker exec -it 9ad13a11b2d5 sh
/ # vault kv put secret/weather-service weather.username=demouser weather.password=demopassword
Get "https://127.0.0.1:8200/v1/sys/internal/ui/mounts/secret/weather-service": http: server gave HTTP response to HTTPS client
/ # export VAULT_ADDR="http://127.0.0.1:8200"
/ # export export VAULT_TOKEN="myroot"
/ # vault kv put secret/weather-service weather.username=demouser weather.password=demopassword

Now add for QA and prod profile
docker exec -it 9ad13a11b2d5 sh
/ # vault kv put secret/weather-service/qa weather.username=qauser weather.password=qapassword

Build microservice
ritgirdh$ cd microservice/
ritgirdh$ mvn clean install
....
Run
docker run -d -p8080:8080 weather-service -spring.active.profile=qa
curl -ivk http://locahost:8080/weather In qa Sunny In prod Rainy
Now make change in vault and see whether its getting reflected in the application
Happy learning!
