UPDATE: hivemind-docker supporting communities

Months ago I wrote a suite to make hivemind easy to deploy with docker (https://steemit.com/utopian-io/@drakos/hivemind-easy-deployment-with-hivemind-docker). This an update to support communities.

The latest hivemind branch that supports communities is 214-core (https://github.com/steemit/hivemind/tree/214-core) but it hasn't been yet merged into the master branch and their dockerhub image hasn't been updated (the current one is 4 months old). That's probably why nobody was aware of that branch!

Hivemind-communities requires a resynch and reindex, given the added columns in a few postgres tables.

Added features to hivemind-docker

https://github.com/Jolly-Pirate/hivemind-docker

• Postgres dump for local backups (./run.sh dumpdb)
• Support for communities using 214-core, I built a docker image and integrated that in the ./run.sh build command. You can always build your own image, just tag it hivemind:latest and you're good to go.
• Additional test commands:
  ./run.sh testhivecom - test a hive-communities API call to hivemind
  ./run.sh testjussicom - test a hive-communities API call to jussi

Update procedure

Requirements: 240GB for the database and 50GB for the dump file.

@emrebeyler has updated his hivemind (https://steemit.com/hive-101863/@emrebeyler/announcing-a-new-hivemind-communuties-node-https-hivemind-communities-emrebeyler-me), we will use that in our update procedure.

• Stop hive and postgres (jussi too, optionally)
  ./run.sh stop all
./run.sh stop jussi
• Delete the pgdata folder
  sudo rm -rf pgdata
• Initialize a fresh database
  ./run.sh initdb
• Edit the .env file and update DB_DUMP_URL to this
  DB_DUMP_URL=https://hivemind-communities.emrebeyler.me/dumps/hive_latest.dump
• Start postgres and import the latest dump
  ./run.sh start postgres
./run.sh importdb
• Finally, start hive and let it synch the missing blocks
  ./run.sh start hive
• If using jussi, add the following to the DEV_config.json file

    {
      "name": "bridge",
      "translate_to_appbase": false,
      "urls": [
        ["bridge", "http://hive:8080"]
      ],
      "ttls": [
        ["bridge", -1]
      ],
      "timeouts": [
        ["bridge", 30]
      ]
    }

and start it
./run.sh start jussi
