pm2-runtime: env spawn E2BIG

[dmpvost]

What's going wrong?

When I start my app with pm2-runtime in gitlab CI.
The current env is inherint from gitlab env.

And it appear that it's too big. PM2 error: Trace: Error: spawn E2BIG
The command filter_env is not available for pm2-runtime

 }

How could we reproduce this issue?

Try to start pm2-runtime under GitlabCI

I forgot to share my twix, rewrite the variable env only with my usage.

The problem is that gitlab have too much argument in args.

I have reset all variable env just for this command with env -i
and add just the strict minimum arguments

env -i PWD="/app" HOME="/root" NODE_VERSION="12.13.0" pm2-runtime

Work fine

@dmpvost pm2-runtime will not be available if you are doing env -i , how are you managing this ?

[dmpvost]

Like that, I just copy paste my case, some variable are maybe useless for you

if [ "${CI_ENV}" == "true" ]
then
  env -i NODE_OPTIONS=--max-http-header-size=79000 ROARR_LOG="true" YARN_VERSION="1.19.1" NODE_ENV="${NODE_ENV}" PWD="/app" HOME="/root" NODE_VERSION="12.13.0" TERM="xterm" SHLVL="1" PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" pm2-runtime ${pm2_conf} --env "${target}" --node-args="--max-http-header-size=80384" --max-http-header-size=81000
else
  pm2-runtime ${pm2_conf} --env "${target}" --node-args="--max-http-header-size=80384" --max-http-header-size=81000
fi

great thanks a lot @dmpvost , I think that PATH env var is important
