Available options:

• ''DISCORD'' - Set with your discord token id (Refer to HELP section) - To enable discord feature (GetFaucet + NodeRegistration + DynamicalIP)
• ''DYNIP'' - Set with "0" if you host under static public IP or "1" if you host under dynimic public IP to enable update IP feature
• ''WALLETPWD'' - Set with "YourCustomPassword" if you want to use a custom wallet password.
• ''NODE_MAX_RAM'' - The app node will auto restart if RAM usage goes over this % treshold. Default to 99%.
• ''TARGET_ROLL_AMOUNT'' - The max number of rolls you want to hold. It will buy or sell rolls accordind your MAS balance and the targeted amount. Default value to 2. set to 0 to disable.

Manage your node:

• Start the container in detached mode:

docker compose up -d

• See the node logs:

docker compose logs

• Filter to get only Massa-guard logs:

docker compose logs | grep Massa-Guard

• To enter your container:

docker exec -it massa-core /bin/bash

• Using massa client:

docker exec massa-core massa-cli get_status

Create an empty folder to mount in our container /massa_mount path or store your wallet /nodekey/stacking_key/config.toml into this folder if you have it:

• wallet.dat
• config.toml
• node_privkey.key
• staking_keys.json

/!\ If don't have this file, leave your folder empty, massa-guard will create a wallet and node key and automaticaly stake wallet for you. This files will be backup on your mount point by massa-guard.

To get your discord token, refer to https://www.androidauthority.com/get-discord-token-3149920/

Logs from your running docker will accumulate with the time. To avoid the disk to be full, you can setup log rotation at Docker level.

Create or edit the file /etc/docker/daemon.json

{
  "log-driver": "local",
  "log-opts": {
    "max-size": "15m"
    "max-file": "5"
  }
}

We recommend the use of watchtower to automagically pull the latest version of the docker image when available. Just add the following lines to add a new service in your docker-compose file:

...
  watchtower:
    image: containrrr/watchtower
    container_name: watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    command: --stop-timeout 360s --interval 300 massa-core
...

IPV6 is disabled by default. To enable it in massa node edit the massa_mount/node_config.toml file. Set the bootstrap_protocol field under bootstrap section to "Both"

This part is higly experimental and has not been actively tested.

• Create or edit your host /etc/docker/daemon.json to add:

{
  "ipv6": true,
  "fixed-cidr-v6": "fd00::/80"
}

• Restart docker service to reload config setting
• Allow MASQUERADE for ipv6

ip6tables -t nat -A POSTROUTING -s fd00::/80 ! -o docker0 -j MASQUERADE

• Create a container which dynamicaly edit your iptables rules for port redirection

docker run -d --restart=always -v /var/run/docker.sock:/var/run/docker.sock:ro --cap-drop=ALL --cap-add=NET_RAW --cap-add=NET_ADMIN --cap-add=SYS_MODULE --net=host --name ipv6nat robbertkl/ipv6nat

Build a massa-node container wich include some automation features from a community image with Massalabs agreements

• [WATCHDOG]
  • Restart node when hang or when ram consumption exceed 90% (Value can be adjust)
  • You host your node under a dynamical IP? massa-guard will watch IP change and update your config.toml and push IP updates to massabot.
  • Push public IP or public IP change to massabot (Need to set discord token in /massa_mount/config/config.ini)
  • Logs his actions over /massa_mount/logs/ and backup node logs before restart if necessary.
  • Autoget MAS faucet on Discord 1 time by day (Need to set discord token in /massa_mount/config/config.ini)
