jwt-agent obtains a JSON Web Token (JWT) from a JWT server, and keep refreshing it not to expire. It is running in the background unless the -f option is specified.
Usage: jwt-agent [-s URL] ... [-l user] [-f] [-t timeout]
jwt-agent --status
jwt-agent --stop [-t timeout]
jwt-agent --version
When the -s option is not specified, JWT_SERVER_URL environment
variable is used. When the -l option is not specified, LOGNAME
environment variable is used.
The jwt-agent asks a passphrase at the start up to obtain a JWT, which is provided by a JWT server. The jwt-agent also accepts the passphrase by the standard input. The jwt-agent does not stop unless it is explicitly stopped, or some error happens.
By default, the jwt-agent stores a JWT at
/tmp/jwt_user_u$UID/token.jwt, which can be changed by
JWT_USER_PATH environment variable.
When multiple -s options are specified, the jwt-agent atemmpts to retrieve the JWT in order if the server is not working. If th passphrase is incorrect, the program terminates at that point. Also, the jwt-agent exits if all URLs are not working.
jwt-agent --status checks the running status of the jwt-agent.
jwt-agent --stop stops the jwt-agent execution.
jwt-agent --version displays the version number.
jwt-agent-core is written in Go. Go 1.18 or later is required.
