Docker i2pd daemon on Alpine Linux with auto config using env vars

Allows to specify i2p tunnels (client/server) providing key in env (or generating it automatically)

Available on hub.docker.com as: darktool/i2p

env

• CLIENT: client tunnels definition, default undefined
  • 80:nginx:8080:KEY
  • 80:nginx:8080: new key created
  • nginx:80: new key created
• HIDDEN_I2P: server tunnels definition, default undefined
  • TYPE:HOST:PORT:KEY
• BANDWIDTH:
  • X (unlimited): good for servers or fast clients (default)
  • P (2048): good for slower client
  • O (256)
  • L (32)
• SHARE: forwarding traffic share limit, default 25%
• LENGTH: tunnels length, default 3
• CONNECTIONS: connections count, default 12
• LOGLEVEL: default error

tunnel type

• client: for accessing remote as local docker via i2p
• server: to provide server tcp tunnel via i2p (similar to Tor Hidden Service)

• irc

exposes

• 4444/tcp: http server
• 4447/tcp: socks server

key management tools

These tools are available in docker

• keygen: generate and output key
  • usage: docker run --rm darktool/i2p keygen: make key and write to stdout, default key type 7 == ED25519-SHA512 (EDDSA-SHA512-ED25519)
• keyinfo: output key info
  • usage: echo $KEY | docker run --rm darktool/i2p keyinfo: key info for base64-encoded i2p key
