from kourou.

@Aschen According to the Elasticsearch 7.x documentation this is still needed on Linux https://www.elastic.co/guide/en/elasticsearch/reference/7.x/vm-max-map-count.html

I have 65530 and I never had any trouble but when I'm running Kuzzle v1 with ES 5 then I have to increase it

$ cat /proc/sys/vm/max_map_count

Can be useful:

• Ping Redis and ElasticSearch urls (default urls or custom urls)
• Check lib installs (os dependant):
  bash-completion
  build-essential
  curl
  g++
  gdb
  git
  gnupg
  libfontconfig
  libzmq3-dev
  python3
  procps
  wget
  libunwind-dev
• Node version check (build and kuzzle node version) with mismatch check
• check docker compose install
• check if an admin exists
