mastodon-discord

Relays mentions of the wiki's Mastodon status account from the accounts in ALLOWED_ACCTS to a Discord channel, as a reply to the alert message a Mastodon reply answers. It runs every minute from an EventBridge rule in femiwiki/infra aws/lambda.tf. deploy.yml sets these variables, the two tokens from this repository's secrets:

• MASTODON_INSTANCE: e.g. https://mastodon.social
• MASTODON_TOKEN: scopes read:notifications read:statuses
• ALLOWED_ACCTS: comma-separated, e.g. lens0021,someone@example.org
• CURSOR_PARAMETER: SSM parameter holding the last notification seen
• DISCORD_BOT_TOKEN: a bot that can view, read history in, and send to the channel, with the Message Content intent
• DISCORD_CHANNEL_ID: the channel Grafana posts alerts to

grafana-github

Keeps one issue in femiwiki/infra per Grafana alert rule labelled impact=operators. Grafana's webhook contact point calls the function URL from femiwiki/infra aws/lambda.tf; the first firing opens an issue named after the rule and its start time in KST, such as Disk almost full (10/3 21:55 KST), and later notifications become comments while it is open. New issues get the alert label. deploy.yml sets:

• GITHUB_APP_CLIENT_ID: the alerts GitHub App, installed on femiwiki/infra with Issues read and write
• GITHUB_APP_PRIVATE_KEY: that App's private key
• GITHUB_MENTION: @femiwiki/pager, mentioned in each new issue
• GITHUB_REPOSITORY: femiwiki/infra
• WEBHOOK_TOKEN: the bearer token Grafana sends
