Change of port number (left side) not working

[bigbeka]

I have tried to change port (left side) from 8080 to say 95 redirects to about:black page.

I have also tried to change right side to 95 and the env port from 8080 to 95, didn't work.

Only port 8080 on all sides works.

I am not sure if it is a bug or what.

Here is my yml:

`version: '3' services: picsur: image: ghcr.io/rubikscraft/picsur:latest container_name: picsur ports:

• '95:8080' environment:

  PICSUR_HOST: '0.0.0.0'

  PICSUR_PORT: 8080 PICSUR_DB_HOST: picsur_postgres PICSUR_DB_PORT: 5432 PICSUR_DB_USERNAME: picsur PICSUR_DB_PASSWORD: picsur PICSUR_DB_DATABASE: picsur

  PICSUR_ADMIN_PASSWORD: picsur

  Optional, random secret will be generated if not set

  PICSUR_JWT_SECRET: long_string PICSUR_JWT_EXPIRY: 1d

  Maximum accepted size for uploads in bytes

  PICSUR_MAX_FILE_SIZE: 128000000

  No need to touch this, unless you use a custom frontend

  PICSUR_STATIC_FRONTEND_ROOT: "/picsur/frontend/dist"

  Warning: Verbose mode might log sensitive data

  PICSUR_VERBOSE: "true"

  restart: unless-stopped picsur_postgres: image: postgres:14-alpine container_name: picsur_postgres environment: POSTGRES_DB: picsur POSTGRES_PASSWORD: picsur POSTGRES_USER: picsur restart: unless-stopped volumes:

• /home/config/picsur:/var/lib/postgresql/data `

the yml you posted should just work fine. If it doesnt there is probably something wrong with your docker setup. Have you tried changing it to for example 8095? Because a low port number requires extra permissions to be used.

[bigbeka]

Thats right, 8095 works.

I will have to do some reading on Docker's below 1024 ports and required permissions.

For some reason, other 20 or so containers are working fine on the same docker instance with ports ranging from 80 - 9x.

Any readup suggestion on the low number port permissions on Docker would be appreciated.

Many thanks for your hard work, it is very helpful! As is I could deploy it to my production env for the website picture hosting. 👍

If the others are working, are you sure there isnt something else bound to port 95? You could always just dig up the docker logs for more info. Might I also ask what your reasoning is for wanting to use port 80-9x? And not just port 8080-809x.

[bigbeka]

No, nothing else is taking up port 95 as I am trying to use ports 80 and onwards (one port at a time for a service). 😅 List of ports PXDocker (Used): 80:NGINX 81:NGINX Manager WebUI 82:Filebrowser 83:Recipes 84:Audiobookshelf 85:jellyfin 86:Syncthing 87:metube 88:changedetection 89:vimflow 90:tubesync 91:Paperless 92:filestash 93:handbrake 94:immich 95: #Not in use 96:watchyourlan 97:PhotoPrism 98:invoiceninja

8080:picsur

All the ports from 80 - 98 are working fine.

Now that you mention it, having removed picsur from 95 to 8080, port 95 on the same IP is spitting out "ERR_UNSAFE_PORT".

Not sure what that is about.

That probably means something else is running on that port, a quick google on "how to find out what program is using which port linux" should probably help you track it down.

Thank you, I’ll probably run an Nmap scan on my host or something.On 26 Sep 2022, at 18:49, Rubikscraft @.***> wrote: That probably means something else is running on that port, a quick google on "how to find out what program is using which port linux" should probably help you track it down.

Unrelated but this is the reason: https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

Port 95 is assigned for something else. Yes I thought I could just run 80 and onwards ports as a list.
