TLDR: Docker won't spin up more then 250 containers.
I'm deploying a cluster of 3 docker services to a swarm with 2 nodes. 2 of the services need to contain 1 container (have a
replicas: 1 in the
docker-compose file), and the third service need to have 300 containers (have a
replicas: 300 setting).
The problem is it's spin up those 3 services, the first two with 1 container each (work like they should), and the third service spin up 248 containers out of 300 (I see this when I do
docker service ls). I try to search if there is a limit of the service or swarm but couldn't find any.
I will much appreciate any help I can get.
- If it's matter, each node with a 30GB RAM and 8 cores, and I use only 1/3 of the RAM.
