spark container name diff

[liuxiaocs7]

I execute the statement just as follow:

# Install Core with Spark Connector, Nebula Algorithm, Nebula Exchange
curl -fsSL nebula-up.siwei.io/all-in-one.sh | bash -s -- v3 spark

The container name is spark-master-1 rather than spark_master_1?

And here maybe confusing.

Thanks, @liuxiaocs7 indeed, the different naming conventions were used in different env from my own ones, I'll do some study(on when/how it differentiated) and fix this soon

I think the docker-compose.yaml in spark folder has no container name specified for master. If that's true, I'll try to fix it.

  master:
    networks:
      - nebula-net
    volumes:
      - '${PWD}/:/root'
    image: 'bde2020/spark-master:2.4.5-hadoop2.7'

you are right, explicitly specify its container_name should do the job(to avoid naming convention), welcome to your PR :). Thanks! I suggest following a similar naming principle of other containers with container_name, that is no space or connecting char like sparkmaster, I'll update my blog posts accordingly after your pr merged.

background:

• implicitly provided container_name will end up depending on docker compose versions.
• docker-compose and docker compose are different
