Restrict To Specific Containers

[adamzero1]

I'm wondering if it would be possible to restrict the list of availble containers?
E.g 1 host with 2 projects, would be good if you could restict to only show containers from 1 project

[amir20]

Hmm...It's not possible right now. But I could add it. What's your use case? Is it that important to hide other containers for you?

[adamzero1]

Thanks for getting back so quick!
I was hoping to use/include this with mdoq the premise being there could be multiple projects on a single server. With the app mounting the docker.sock it can obviously see everything. Which is not ideal, as we need to keep seperation between projects.
It's something I'm happy to add and create a PR for, if you could provide some build steps so I can test locally before creating the PR?

[amir20]

Nice. That would be a good addition to mdoq.

It would be really nice to get a PR. I am really busy at work so won't have much time to work on this until next week. But I can review and merge.

Here are some things that might get you going with building Dozzle:

1. Install nodejs v12
2. Install go v1.12.7
3. Install packr globally by doing go get -u github.com/gobuffalo/packr/packr outside for dozzle
4. npm i to install node mods
5. You can look at the automated build file script to understand how I build everything.
6. npm start should automatically do go mod download and start dozzle at port localhost:8080

Here is what you would need to change:

1. Add a new string flag that can be configure the regex (or whatever you decide to do) at https://github.com/amir20/dozzle/blob/master/main.go#L38
2. Possibly add the logic at https://github.com/amir20/dozzle/blob/master/main.go#L135 to filter based on the flag.
3. If it's important, then you would need to also update https://github.com/amir20/dozzle/blob/master/main.go#L148 to not allow logs of filtered docker images

I hope this helps. Let me know if you have any questions.

Nice one, PR raised

[amir20]

Should be fixed in #85

[amir20]

@adamzero1 Released v1.12 can you try it out?

[adamzero1]

@amir20 looks to be working

version: "3"
services:
  dozzle:
    container_name: dozzle
    image: amir20/dozzle:latest
    environment:
      - DOZZLE_CONTAINERRESTRICTIONS=6893-.*
      - DOZZLE_TAILSIZE=100
      - DOZZLE_FILTERNAME=6893-.*
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 9999:8080

Only issue is we have now lost the ability to pass in any other kind of filter. We are forced to filter on name. I had thought you wanted it more generic. where you could pass in something like:

DOZZLE_FILTERNAME=name=6893-.*

It still works for what I need though, nice one!

[amir20]

Ah I see. Did you have that in your PR? I may have not pulled the latest. Sorry if I missed it. I looked at the filters and it seemed like name would be the most common since it won't change.

On a plus a side, you don't need *. You should just be able to do foo which will work just like .*foo.*. That was the nice part of using the docker API directly.

[amir20]

I now see https://github.com/amir20/dozzle/pull/84/files#diff-210c31cd49f34ac9a1fcc99dd77d9030R48. Maybe it makes sense to add that back? I like that you can also filter based on labels. Which will probably make a lot of sense for people.

[amir20]

@adamzero1 I added this back in #87.

[adamzero1]

Sorry have had a hectic few days, yeah opening up so it wasn't name filter specific would be better overall I feel.

[amir20]

No worries. Sounds good. The feature should be deployed now. Thanks for your help and PR. It was an interesting feature I hadn't thought of.
