topics

• our requirements
• some history
• docker swarm
• demo time

concepts

• node
• stack
• service
• task

setting up your own swarm

• manager
• worker
• other?

choose our base

more traditional distributions

more advanced or specific distributions

setup a swarm

Chosen base distribution:

system

$ apk add --update --no-cache docker
$ rc-update add docker default
                        

certificates

communication between client and server will be encrypted

client config

to communicate with our server(s) we have to setup some environment variables

export DOCKER_HOST=tcp://192.168.250.31:2375
export DOCKER_CERT_PATH=$(pwd)/client-cert
export DOCKER_TLS_VERIFY=1
                        

setup the swarm

# docker swarm init \
    --advertise-addr=[internal server ip]
# docker swarm join-token \
    -q worker
# docker swarm join \
    --token [worker token] \
    [internal master server ip]
                        

simple check swarm status

$ docker node ls
$ docker service ls
                        

docker service

create/manage a single service within a swarm

docker stack

create/manage an application stack within a swarm

deploying a simple stateless application

challenges encountered

• create stateless images
• create swarm configuration
• registry? self hosted? docker hub?
• what if I want to add more applications

What if I want more applications

Enter traefik

I like visual representation

deploying pimcore, there is state, a database, ...

additional challenges

• prepare your database
• how to handle/store state
• handle scheduled jobs

are we still missing something

• central logging
• metrics / alerting

topics

• our requirements
• some history
• docker swarm
• demo time

pimcore 5

magento 2

summarized

• we can run php applications
• we can see where what is running
• we have some monitoring and alerting
• we have central logging
