Segmentation fault (alpine)

[Tarocch1]

• code-server version: 1.868-vsc1.33.1
• OS Version: alpine 3.9.3 (not in docker)

Description

If source code folder (code-server-1.868-vsc1.33.1) exists, code-server run fine, otherwise, code-server gets segmentation fault.

Steps to Reproduce

1. Unzip code-server-1.868-vsc1.33.1.zip in /root
2. yarn
3. Add target option as alpine in /root/code-server-1.868-vsc1.33.1/packages/server/scripts/nbin.ts
4. export NODE_ENV=production
5. apk add libxkbfile-dev libsecret-dev
6. yarn task build:server:binary
7. cp /root/code-server-1.868-vsc1.33.1/packages/server/cli-linux-x64 /usr/local/bin/code-server
8. code-server -H -N --disable-telemetry (work fine)
9. mv /root/code-server-1.868-vsc1.33.1 /root/code-server-1.868-vsc1.33 (use mv as rm)
10. code-server -H -N --disable-telemetry:

some error here at alpine (no docker) using lxc

wget https://github.com/codercom/code-server/archive/1.903-vsc1.33.1.zip
unzip 1.903-vsc1.33.1.zip
cd code-server-1.903-vsc1.33.1
yarn
nano packages/server/scripts/nbin.ts

take a look at = coder/nbin#3 (comment)

const bin = new Binary({
        mainFile: path.join(rootDir, "out", "cli.js"),
 target: 'alpine',
});

now last step

npm_config_build_from_source=true NODE_ENV=production npm_config_unsafe_perm=true yarn task build:server:binary --force
cp packages/server/cli-linux-x64 /usr/local/bin/code-server
code-server -H -N --disable-telemetry

same error = segment-fault after openning url

mv /root/code-server-1.903-vsc1.33.1 /root/code-server-1.903-vsc1.33
code-server -H -N --disable-telemetry

alternative install:

cd /
mv /root/code-server-1.903-vsc1.33.1 /opt/code-server-1.903-vsc1.33.1
cd /opt/code-server-1.903-vsc1.33.1
rm /opt/code-server-1.903-vsc1.33.1/packages/server/cli-linux-x64
rm /usr/local/bin/code-server

This is because your native modules need to be built on alpine as well.

[Gooseware]

This is an issue because your docker image now suffers from this fault

You ran out of mem. Likely isn't an issue with the docker image

[tobbenb]

I have been trying to get code-server working inside an alpine container, and had the same issue as the OP.
The problem is that the node_modules in the root of the directory you start the build in is needed when opening the webui.
From the build, the needed file is:
/source-folder/packages/server/cli-musl-x64
The directory needed is:
/source-folder/node_modules

The binary can be located where you want, but the node_modules directory needs to be located at the same place as during build.

Is this a bug in the build process or do I need to supply something to get the node_modules included in the binary?

[arvati]

gist to install code-server using alpine lxc

I needed to compile from source again to get it working.

[TGATM-Magnus]

Has any one managed to actually get a working docker image here? I tried starting from a blank alpine:latest image today with the help of arvati's gist but somehow the build process is difficult to get to complete (at least for me XD). Also taking tobbenb's input and trying to fake the build by putting the already built binary together with the code repository after initializing node_modules doesn't really resolve the segmentation issue...the interface loads (I even get past the login screen) but then the process dies.

[arvati]

these are packages installed on alpine. Check if some of them are missing before start compilation

Thanks for that list - if I find the time I will try it tomorrow again...for now I at least got it to work on minideb.

[Merith-TK]

When running pre-built binary
(note, that is alpine Linux on real hardware, Its just my rice that looks windowsy)

EDIT: Same issue on Firefox

[nhooyr]

See #1306

[nhooyr]

Nvm, this should be fixed. If this still occurs, please feel free to reopen.
