Docker Swarm Clustering for multiple Docker nodes 2

Container Orchestration Engines 3

Benefits Less complexity Docker API Ecosystem Scheduling Strategies Constraints Filters Rescheduling DNS 5

Docker Swarm Cluster is the new normal Cluster aware 6

Effective Docker Swarm

Images docker build Build a custom image Run a container taking up a limited resource Twice 8

Images Constraint Affinity Public registry Private registry 9

Volumes docker volume Create a volume Write some data Read it back 10

Volumes Distributed file system Store data off-cluster Data volume containers Back up and restore! 11

Networks Run a container with published port(s) Refer to another container by name 12

Networks docker network Overlay networks DNS 13

Security IANASE Swarm TLS Overlay networks Container Watchtower Docker Bench 14

Security Daemon AuthZ plugin Updates Node seccomp AppArmor 15

Service Discovery Service registration Service discovery Load balancing 16

Service Discovery DNS Interlock etcd + registrator + confd + haproxy/nginx consul + registrator + consultemplate + haproxy/nginx 17
