 Posted: Sun May 26, 2024 1:39 pm Post subject: docker beyond wiki fails here |
 |
|
Docker noob here.
Wiki achieved fine.
But trying pgadmin4 official docker image fails.
IIRC app should be accessible through http://localhost:80
| Code: | | EDIT: sysctl net.ipv4.ip_forward=1 |
is here too.
Connection is rejected.
telnet detects something is there.
No idea how to investigate...
Any simpler docker image I could use to test my docker install?
Thks 4 ur attention, interest & support.

Beside unreachable, is there any other error?
Does the container actually running?
The simple one could be | Code: | | docker run -it busybox |
You don't need to manually change forwarding, docker will do that for you. |

Container is gone after ~ 2 mn.
Short duration may indicate init issue?

If you start your container without the '-rm' option then, there should be some log for the container. can you try | Code: | | docker logs <container name> |
to see if anything were register? |

CGROUP_HUGETLB can't be activated here. Wiki says optional.
Maybe I should try default kernel .config?

| Quote: | | trying pgadmin4 official docker image |
, which image? A image exist on docker hub does not make if official, anybody can publish images into docker hub.
Can you share the command used for start this container? or if you want you can remove this container, but start a new container. but share the command use to start new container.
It is unlikely your kernel need to changes in order to run docker, however I don't know if there something required for run pgadmin4. have you find anything defined by pgadmin4 developler? |

I think your current situation is not Gentoo/Docker issue, it is container configuration issue.
So depend on what you like to do, Do you like to resolve the issue for not able start pgadmin4? or you prefer to learn more about docker debugging strategy?
For quick start pgadmin4, I suggest you change the binding to only IPv4, I have seem some docker images have application limit so bind to IPv6 will cause problem, so you can try | Code: | | docker run -p 0.0.0.0:80:80 -e PGADMIN_DISABLE_POSTFIX=1 -e ... |
This will disable the postfix start in the entrypoint.sh and will let the script continue to start gunicorn for web service. If that does not work try | Code: | | docker run -p 0.0.0.0:80:80 -e PGADMIN_DISABLE_POSTFIX=1 --sysctl net.ipv6.conf.all.disable_ipv6=1 -e... |
This is to ensure the container instance not using IPv6 stack.
If you wish to know more about docker debugging, we can try to start the container with shell (i.e. will not run the entrypoint.sh) In this way we can examine the container environment and execute step by step follow the entrypoint.sh to understand where exactly the cause. | Code: | | docker run -it --entrypoint /bin/sh -e... |

There apparently have another container environment variable "PGADMIN_LISTEN_ADDRESS=", so please also try to add it in to command line for example | Code: | | docker run -p 0.0.0.0:80:80 -e PGADMIN_DISABLE_POSTFIX=1 -e PGADMIN_LISTEN_ADDRESS=0.0.0.0 -e ... |

That's what so nice on Gentoo forums...
Unexpected and interesting ideas and proposals. +1
AFA quick start is concerned, IP4+IP6 made it run.
AFA pgadmin4 Desktop is concerned, I never found out how to (e)build version since v7.
Arch & Debian have binpkg though.

Mean you made changes to system (or kernel) to enable/disable IPv6? |

Kernel level.
Had a minimal kernel for riseup-vpn which requires IP4+6.
Still have to retrieve and remove riseup-vpn only kernel options.
Docker is pgadmin4 Server, not Desktop.
