== Camel Example HashiCorp Vault
2+
3+
This example shows how `camel-hashicorp-vault` can be used to configure beans using data from HashiCorp Vault
4+
5+
=== How to run
6+
Run HashiCorp Vault
7+
8+
docker run --cap-add=IPC_LOCK -e 'VAULT_DEV_ROOT_TOKEN_ID=myroot' -e 'VAULT_DEV_LISTEN_ADDRESS=0.0.0.0:8200' -p 8200:8200 hashicorp/vault:1.16.1`
9+
10+
Go to `http://localhost:8200/ui/vault/secrets/secret/kv/list` login with method Token and token `myroot` and create the following secrets:
11+
12+
* a secret named `myDatabase`
13+
* a secret data `myPassword` with value `mysecretpassword`
14+
* a secret data `myUsername` with value `postgres`
15+
* a secret data `myJdbcURL` with value `jdbc:postgresql://localhost:5432/postgres`
16+
17+
image::img/secret-database.png[]
18+
19+
Run the database container
20+
21+
docker run -p 5432:5432 --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword postgres
22+
23+
You can run this example using
24+
25+
mvn spring-boot:run
26+
27+
To execute the routes:
28+
29+
1. verify the table is empty (no data on response)
30+
31+
curl http://localhost:8080/api/cars
32+
33+
2. insert data
34+
35+
curl --header "Content-Type: application/json" --request POST --data '{"brand": "Ford", "model": "Mustang", "year": 2024}' http://localhost:8080/api/cars
36+
37+
3. verify the data has been persisted
38+
39+
curl http://localhost:8080/api/cars
40+
41+
