<SOLVED> New install of Gitea/Drone - unable to auth into Gitea

Installing Gitea and Drone as docker containers on a test system. This playbook has been working, but something new has happened … From the Drone Welcome screen any attempt at auth into Gitea results in an invalid_request coming back.

Gitea is set up with a default admin user droneadmin, the oauth2 application is created and the client_id and client_secret are stored in an .env file for docker to read as it all starts up (via systemd). The ExecStart looks like this

ExecStart=/usr/bin/docker run --rm --name drone \
    -e TZ=America/New_York \
    --env-file "/stuff/gitea/drone/drone.env" \
    --env-file "/stuff/gitea/gitea/admin.tokens" \
    -p 3001:80 \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /stuff/gitea/drone:/data \

and the drone.env and admin_tokens looks like this



# These two for drone-runner and drone-runner--exec

# Can also specify token by adding ",token:<32-char-token>"



With DRONE_LOGS_DEBUG enabled, a sample docker logs drone --follow results in this

The associated Gitea logs are

2022/11/22 18:05:26 [637d55b6] router: completed GET /login/oauth/authorize?client_id=17408453-6795-4410-89d3-84584fcfea16&redirect_uri=http%3A%2F%2Fxeon.local%3A3001%2Flogin&response_type=code&state=4d65822107fcfd52 for, 303 See Other in 0.2ms @ context/auth.go:28(context.Toggle)

The Drone error msg "request": "/login?error=invalid_request\u0026error_description=PKCE+is+required+for+public+clients\u0026state=4d65822107fcfd52", is interesting …

This happens for all variations in a clean system, starting from the Drone Welcome screen - all immediately back to the invalid_request

  • Only droneadmin user exists in Gitea and Drone, click Continue on Welcome screen, log into Gitea as droneadmin
  • New user registered in Gitea (not Drone), log out of Gitea, click Continue on Welcome screen, log into Gitea as that new user
  • New user registered in Gitea (not Drone), stay logged in, click Continue on Welcome screen
  • New user upgraded to Admin in Gitea
  • New user created in Drone via drone user add --admin newuser to match user in Gitea

Just regenerated the Oauth2 DRONE_GITEA_CLIENT_SECRET in Gitea for the newuser, updated the value in the drone.env, restart the Drone container.

Same problem happening

Possibly more information ? On a bare fresh install of gitea/drone, using the drone cmdline to get info drone info shows a couple of duplicate proto lines

[email protected]:/stuff/gitea$ cat /stuff/gitea/drone/drone_cmdline.env

# Used for drone cmdline access
export DRONE_TOKEN=17Ac4fb4Bcb4a58ccf8aE6e27C1bB65C
export DRONE_SERVER=http://xeon.local:3001

# Usage:
# source /stuff/gitea/drone/drone_cmdline.env
# drone info
[email protected]:/stuff/gitea$ source /stuff/gitea/drone/drone_cmdline.env
[email protected]:/stuff/gitea$ drone info
2022/11/23 09:53:18 proto: duplicate proto type registered: PluginSpec
2022/11/23 09:53:18 proto: duplicate proto type registered: PluginPrivilege
User: droneadmin

Also, when I compare the fresh install on xeon.local to a currently working install on another system (identical setup) I notice these differences in the /stuff/gitea/gitea/conf/app.ini file

  • [security] section is missing the SECRET_KEY and INTERNAL_TOKEN items
  • [oauth2 section is missing the JWT_SECRET item

How are those generated ?


The problem was that the oauth2 application being generated in Gitea (via api) was not marked as a confidential one. Simply had to add

"confidential_client": true

To the body json in the api call
