Installation instructions for Alpine Linux #188

demyxco · 2019-05-15T09:31:57Z

Hello I've read #180 and tried to use the same libs in a Docker build but it just fails at 64%.

Can't seem to figure out what the error means, any help is appreciated! Thanks!

It looks like crash logs are not supported on Alpine. You can turn off the easy logging crash log compiler definition in CMakelists.txt

You can turn off the easy logging crash log compiler definition in CMakelists.txt

Remove line 114?

external/easylogging++.cc

MisterTea · 2019-05-15T22:59:17Z

No, remove this "-DELPP_FEATURE_CRASH_LOG"

demyxco · 2019-05-15T23:08:59Z

Thanks that did it. Seems like it fails to run when the build dependencies are deleted.

MisterTea · 2019-05-16T00:49:37Z

Is there a way to detect alpine linux in cmake? If so, we could make that fix permanent.

This seems to work for me, others can chime in and do some testing.

file(STRINGS "/etc/os-release" ID)

IF(ID MATCHES "alpine") 
  SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DELPP_NO_DEFAULT_LOG_FILE -DELPP_THREAD_SAFE -DELPP_HANDLE_SIGABRT")
ELSE()
  SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DELPP_NO_DEFAULT_LOG_FILE -DELPP_FEATURE_CRASH_LOG -DELPP_THREAD_SAFE -DELPP_HANDLE_SIGABRT")
ENDIF()

demyxco · 2019-05-18T07:50:59Z

Is there anything else I'm missing? Et just won't connect via Docker container. I can ssh just fine into it but not et. I've started the etserver in the container using --daemon flag. Is there something else I'm missing to start up?

Executed script on container up

#!/bin/sh

/usr/local/bin/etserver --daemon
/usr/sbin/sshd -D

Docker command

docker run -it --rm \
--name et \
-v et:/home/demyx/.ssh \
-p 2223:22 \
-p 2022:2022 \
demyx/eternal-terminal

This is a fresh install of Alpine Linux as the host OS so there's no firewalls. I've tried even using the Ubuntu image to see if it was an Alpine thing but same results. Nada.

MisterTea · 2019-05-18T14:10:19Z

What do the et logs in /tmp say? You may need to run in verbose mode.

demyxco · 2019-05-19T00:34:06Z

Keeps saying the same thing:

can you telnet to that machine on port 2022?

demyxco · 2019-05-19T04:27:52Z

Yes, it shows connected.

MisterTea · 2019-05-19T04:55:41Z

Hmm, can you try running latest master on client?

brew install --HEAD et

MisterTea · 2019-05-19T05:34:04Z

Also turn on verbose logging on the server in /etc/et.cfg

This will generate many files in /tmp/et* Please look at all of them to find a meaningful error that we can work with.

MisterTea · 2019-05-19T05:34:18Z

Note that you will need to restart the et service after changing et.cfg

demyxco · 2019-05-20T06:33:18Z

Server starts fine, just won't connect. I could use et client from container to connect to a different (Ubuntu) machine but not from my MacBook to container. I also tried connecting from my Manjaro box to the container, no luck.

Not much logs are generated.

Note that you will need to restart the et service after changing et.cfg

This is a minimal alpine image so there is no systemd or systemctl for me to use.

I'm getting close, et is trying to connect to the host OS instead of the container.

I finally got it! The key was to create an ssh alias ~/.ssh/config on the local computer (my MacBook for example).

Docker Hub: https://hub.docker.com/r/demyx/eternal-terminal

Host example
     HostName domain.tld
     User demyx
     Port 2223

docker run -dit \
-v demyx_ssh:/home/demyx/.ssh \
-p 2223:22 \ 
-p 2022:2022 \
demyx/eternal-terminal

Hi, I'm having compiling issues again. Not sure what you changed but a file is missing:

I am compiling this for Docker so nothing has changed in my Dockerfile, except version changes for Alpine Linux. Every time I build this image, it would git clone a fresh copy of your repo.

demyxco · 2019-08-19T21:52:34Z

Successfully compiled by adding this flag to git clone:

--recurse-submodules

I had a custom CMakeLists.txt for a while but decided to do a sed replace on it to make it compile for Alpine:

sed -i 's/-DELPP_FEATURE_CRASH_LOG//g' EternalTerminal/CMakeLists.txt
