WARNING! dev mode is enabled! In this mode, Vault runs entirely in-memory
and starts unsealed with a single unseal key. The root token is already
authenticated to the CLI, so you can immediately begin using Vault.
You may need to set the following environment variable:
$ export VAULT_ADDR='http://127.0.0.1:8200'
The unseal key and root token are displayed below in case you want to
seal/unseal the Vault or re-authenticate.
Unseal Key: 7Ikm5CEkuxiUAITXgWJb81Hfo7wdymr3gM1igvOEiLo=
Root Token: s.l5QIWgO9MhRc8dqQpuqFEQ5V
Development mode should NOT be used in production installations!

Step 2: Points to be noted in step 1 output.
Dev server is started at port 8200
Vault run in-memory.
Vault is already unsealed with a single unseal key ‘7Ikm5CEkuxiUAITXgWJb81Hfo7wdymr3gM1igvOEiLo=’.
Root token ‘s.l5QIWgO9MhRc8dqQpuqFEQ5V’
To communicate with dev server, we need to set following environment variable in the terminal.
export VAULT_ADDR='http://127.0.0.1:8200'
Development mode should not be used in production installations.
Step 3: Open other terminal and set VAULT_ADDR by executing below command.
export VAULT_ADDR='http://127.0.0.1:8200'
Step 4: Enable kv secret engine at path secret/kv.
$vault secrets enable -path=my-secrets/ kv
Success! Enabled the kv secrets engine at: my-secrets/
Step 5: Write some key-values at path my-secrets/my-app
vault kv put my-secrets/my-app username=krishna123 password=password123
$vault kv put my-secrets/my-app username=krishna123 password=password123
Success! Data written to: my-secrets/my-app
Step 6: Get the secrets.
vault kv get my-secrets/my-app
$vault kv get my-secrets/my-app ====== Data ====== Key Value --- ----- password password123 username krishna123
Step 7: Delete the secrets.
vault kv delete my-secrets/my-app
$vault kv delete my-secrets/my-app
Success! Data deleted (if it existed) at: my-secrets/my-app
$
$vault kv get my-secrets/my-app
No value found at my-secrets/my-app
