Docker SAL and Postgres-SAL

[ryan8382]

We use this SAL product at work and I wanted to set it up at home.

https://github.com/grahamgilbert/docker-sal

 

I have setup my own github repo (https://github.com/ryan8382/unraid) for it and have the containers installing however the way the application is written it is looking for --link postgres-sal:db. I have tried to put that in extra parameters section but then it gives me an error.

The command failed.

 

I had tried to change the postgres-sal container to use host from none on the networking then it gave me a different error.

The command failed.

 

I'm still learning how to use docker so any help would be great. Once i get this working i want to get a puppet server container.

I can't help you with your problem, but I do have a question: Are you making your repository available to all unraid users? IE - do I add it into the repositories list?  (Once your problem is solved at least)

the name of the container you're trying to link to makes up the first half of the link argument in the other container.

 

so if the database  container has name postgres, the link would have to be postgres:db in the other container.

This is the github repo.

As for the linking it looks to be correct. I'm using the default name that the other person used. I'm wondering if there is something up with docker on unRaid. I have tried setting this up on a Ubuntu box and it works no problems.

are you starting the postgres container first ?

 

if it isn't started there is nothing to link to. i've linked containers in unraid before and apart from some issues with the webui regards right clicking icons (which i believe is fixed) , it works.

I'm not an expert with this but I think there is a bug somewhere. I have setup a VM on unRAID running ubuntu with Docker and used the same  commands that they use which is the same thing that i moved into the unraid XML format. It works no issues.

 

I then took the same command at CLI and changed the ports and I get the same error that i posted originally. This is the command I ran.

 

docker run -d --name="sal" -p 89:8000 --link postgres-sal:db -e ADMIN_PASS=pass -e DB_NAME=sal -e DB_USER=admin -e DB_PASS=password --restart="always" macadmins/sal

I'm going to continue to play with it but this should work.

there's no bug, i believe that because one of your containers is set to host as the networking type with no port specified that it's trying to allocate port 80, which it cannot do because that's the unraid webui port.

 

it doesn't fail when in a VM because the VM doesn't have port 80 allocated because it's an entirely different IP address from your unraid host.

[ryan8382]

Well your right there is no bug. I copied the stuff right off the page changed a port and put it in and it works. Maybe tonight i will get it working with the XML stuff.

 

Thanks sparklyballs.
