I have tried to give a custom config file to start the vault server, in the vault.service file and is working as expected.
But if i try to start the vault server in dev mode changing
ExecStart=/usr/local/bin/vault/vault server -dev, in this case service exits.
On the other hand if I manually run /usr/local/bin/vault/vault server -dev, vault server is getting started in dev mode.
Is it possible to run vault server in dev mode using vault as a service ?
After a research I have come to an understanding that, Yes we can run dev mode as a service. Dev mode creates a token in /home/user_mentioned and home for that user should also be created. Or we need to set the home path for that particular user.
