i want integration test for my golang project, and using mongodb transaction. to make it work
i need make mongodb services running replica set

image: golang:1.13

services:
  - name: mongo:4.2
    alias: mongo-svc
    command: ["mongod", "--logpath=/dev/null", "--bind_ip_all", "--replSet=rs0"]

unit_tests:
  stage: test
  script:
    - mongo-svc exec mongo --eval "rs.initiate()"
    - make test

i get error

$ mongo-svc mongo --eval "rs.initiate()"
 /bin/bash: line 95: mongo-svc: command not found
 ERROR: Job failed: exit code 1

i already use another command but still cant find how to do it.

Aliases don’t work in k8s runners, you need to use 127.0.0.1 instead. And the command should be a little bit different. mongo "mongo-svc" --eval "rs.initiate()"
Any way, i suggest you to use this - https://github.com/bitnami/bitnami-docker-mongodb
It’s bootup replica set with Environment variables.
