Ability to set a display name coming from a env var in the title tag and in the page header

[UnclePhil]

Describe the feature you would like to see

I use Dozzle on 16 swarm clusters, and sometimes I've 4 or 5 instances open in the same browser with all difficulties to find the good one.
It will be fine to have a Env var with a display name appearing in the title tag and in the header of the application.

BTW your app is a killer one.
best regards

Describe how you would like to see this feature implemented

• Create a DOZZLE_TITLE envvar
• Inject it in the title tag, and in the header of the nav bar, in-place of under the svg logo

Describe any alternatives you've considered

Isn't this already done?

[UnclePhil]

Sorry,
I totally pass over this setting.
It work perfectly.
already loaded on all clusters

[UnclePhil]

And i rollback,
because when you put the --hostname flag on a swarm implementation in global mode, all swarm host in the right display have the same name. But i need the real host name !!

services:
  dozzle:
    image: amir20/dozzle:latest
    environment:
      - DOZZLE_MODE=swarm
      - DOZZLE_HOSTNAME=${CLUSTER_NAME}
      - DOZZLE_NO_ANALYTICS=true
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 28080:8080
    networks:
      - dozzle
    deploy:
      mode: global
    ...

The display

What would you expect it to do? DOZZLE_HOSTNAME=${CLUSTER_NAME} is it different on each node? I haven't tested it, but if passed correctly, each hostname should change. I am not an expert on how variables work in swarm mode, but maybe you can append something else to it?

[UnclePhil]

${CLUSTER_NAME) is the generic name of the cluster
The cluster is composed of multiple nodes with the pattern -0x
Like the following list
[dcltst01]
dcltst01-01
dcltst01-02
dcltst01-03
dcltst01-04
dcltst01-05

What i hope to see on the header and title is dcltst01,
but i'd like to see each hosts statistics with his own name

That's why i think that a DISPLAY_NAME var will be a good feature.
BTW I understand perfectly your --hostname flags for a host with a very long cloud generated fqdn, but the usage in cluster is not adequate imho.

best regards

[amir20]

You would have to use ${CLUSTER_NAME}-${NODE_ID}.

What i hope to see on the header and title is dcltst01,

However, I don't think this is possible now. Because is swarm mode, each node is hit at random. So the header will change on every page load.

I am not sure what the solution would be. Sorry. If you see something easy, then send a PR.

[UnclePhil]

I'll check that.
and come back to you

[UnclePhil]

HI, i come back to you.
I'm almost ready with a pr for the title tag, but i've still one problem because i'm not a specialist in vue and in go.

where did you fill the effective data in config array that you use in title.ts
I modify the ,

• main.go & args.go to receive the new env var
• config.ts to define the config interface
• title.js to use it

if I set the default value for config it works, but dynamically not

If you have any idea it will be great
best regards
UnclePhil

[amir20]

I think you are going down the wrong path. I am still not sure what you are doing or want here. executeTemplate passes config data in index.go. This template is executed on the node and it is chosen at random. I don't think this is what you want because it would break when the page is reloaded.

Are you just trying to make it so that the chosen host is in the title? If so, --hostname should work already. I am not understand what this new variable would do.

Maybe once I see the PR it will make more sense.

[UnclePhil]

I just add an DOZZLE_SWARMTITLE var loaded on all node, and the put it in title and in the navbar if hostname is not set.
And with your help it work's

i'll made some test tomorrow and i PR it

best regards

[amir20]

I think I know what you are trying to do. Perhaps you should use DOZZLE_HOSTNAME instead and change the behavior when DOZZLE_MODE=SWARM.

I'll most likely ask for that in the PR :) No reason to introduce yet another var that does the same thing as something that already exists.

[UnclePhil]

This one is working with a new variable
but i respect the precedence of hostname over swarmtitle

docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -p 8080:8080  -e DOZZLE_SWARMTITLE=UnclePhil amir20/dozzle:latest

I'm going to check your idea of the behavior in another run

[amir20]

There reason --hostname doesn't work because of here

dozzle/main.go

Line 174 in 5766410

localClient, err := docker.NewLocalClient(args.Hostname)

In Swarm, agents are created on all node. It should probably not take args.Hostname as an argument. I bet if you just remove that, it will just work.

• Amir: 1 line
• Unclephil: 5 line
  And the winner is .... Amir !!

Did you prefer a PR, or you process the change in a next build ??
Line 174 localClient, err := docker.NewLocalClient("")

Many thank's for the support

Easy enough to do on my side

[amir20]

It's merged, but I probably won't release until next week when there are a few more fixes to apply.

[UnclePhil]

I've seem the merge. For the moment I run with my dev release. This is a real nice job, a little bit complicate to dive in. But that's why i love the challenge. Best regards. Ph. Koenig / UnclePhil Le ven. 10 janv. 2025, 17:59, Amir Raminfar ***@***.***> a écrit :
