Configuration

Candebot can be configured via Toml file + environment variables. The need for setting up environment variables when using the Toml file is due to the fact that some of the configurations is sensitive and should not be stored in a file.

Environment variables

All environment variables are prefixed with BOT_. For example, BOT_BOT_USER_TOKEN. If you want to change the prefix, you can set -env-prefix <prefix> flag when running the bot.

The following environment variables are needed in order to run the bot:

• BOT_BOT_USER_TOKEN - Slack bot user token. Used to authenticate the bot user.
• BOT_BOT_ADMIN_TOKEN - Slack user token with admin rights. Used to authenticate the bot user when performing admin actions.
• BOT_BOT_SERVER_SIGNING_SECRET - Slack app signing secret. Used to verify the authenticity of the requests.

There are more environment variables that can be set. Please, check /bot/config.go.

Toml File

By default, ./.bot.toml is used as the configuration file. If you want to change the path, you can set -config <filepath> flag when running the bot.

Please, use the following file as a reference.
