tldr: docker wont spin more 250 containers. i'm deploying cluster of 3 docker services swarm 2 nodes. 2 of services need contain 1 container (have replicas: 1 in docker-compose file), , third service need have 300 containers (have replicas: 300 setting). the problem it's spin 3 services, first 2 1 container each (work should), , third service spin 248 containers out of 300 (i see when docker service ls ). try search if there limit of service or swarm couldn't find any. i appreciate can get. if it's matter, each node 30gb ram , 8 cores, , use 1/3 of ram. i don't think can spin more 250 1 service, due fact of them sitting on same network mean using 250+ ip addresses. unless define custom ipv6 network , try that, you're better off adding network swarm, spin new identical service on swarm on other network tl; dr; define 2 networks , add them service, see if can spin more 250 replicas
