Pro Swarm sample: Fixing to run in current Swarm

[marcellodesales]

Problem

• Current file does not work to deploy in a swarm from newer docker engines
• Apparently artifactory-pro.yml is suitable for docker-compose.yml?

[ec2-user@ip-xx-xx-48-169 ~]$ docker --version
Docker version 17.05.0-ce-rc3, build 90d35ab

• Current behavior does not start because it can't mount the volumes defined

$ docker stack deploy -c artifactory-pro.yml  artfctry

[ec2-user@ip-xxx-xxx-48-169 ~]$ docker stack ps artfctry

Solution

• Replacing the volumes definition to a named one
• Adding the restart policy with a delay
• Adding a placement to be NOT the swarm manager nodes (by default docker documentation)
• Defining the named volume, without the driver

The result with this patch is a runnable installation in a Swarm that can be used to start developing.. What needs to be done:

• Network Placement
• Persistent Volumes
• Logging

Users can define on their own.

$ docker stack deploy -c artifactory-pro.yml  artfctry
Creating service artfctry_postgresql
Creating service artfctry_artifactory
Creating service artfctry_nginx

Could get the app running in EC2 ELB....

Hi @marcellodesales - can you sign JFrog's CLA so I can review and merge?

Thx!

[NasAmin]

I am very interested in this change as well - thanks

[NasAmin]

I am a bit confused, how can we map a named volume to the container's host directory?

[marcellodesales]

@NasAmin You need to use a Docker Volume plugin and write to an EBS volume...

[marcellodesales]

@eldada I can't login to the site... Where can I create an account? It's asking me to Login...

[eldada]

@marcellodesales - go directly to the form

@eldada DONE! SIgned the CLA.
