  • Looks like the output of this line is empty for some reason: https://github.com/getsentry/onpremise/blob/19f4561a9e2abe32dc5eb5a03a332b50f2265b4b/install.sh#L99 Could you run that yourself and see what's going wrong? – BYK Nov 30 '20 at 16:46
  • Docker doesn't have a dedicated RAM pool on Linux (unlike, say, Docker Desktop for Mac, where the hidden Linux VM has a specific memory allocation). A container can use all available system memory unless it's explicitly limited. Can you show the application code you are trying to write that computes or uses this value? – David Maze Nov 30 '20 at 17:50
  • I tried to install `sentry` on docker as i mentioned. but u can see https://github.com/getsentry/onpremise/blob/19f4561a9e2abe32dc5eb5a03a332b50f2265b4b/install.sh#L99 script @DavidMaze – Cyrus the Great Nov 30 '20 at 17:56

I write my answer maybe help to someone!

1 - I pull busybox first:

$ docker pull  busybox 
Using default tag: latest
latest: Pulling from library/busybox

Digest: sha256:9f1c79411e054199210b4d489ae600a061595967adb643cd923f8515ad8123d2

docker.io/library/busybox:latest
alt@mx-alt:~


alt@mx-alt:~
$ sudo docker run --rm busybox free -m 2

2- ./install.sh

Done.

  • So you had an older version of busybox image that was not generating the expected output? If that's the case I'll need to add the pull step into the script, that's why I'm asking. – BYK Nov 30 '20 at 20:20
  • Thanks for this answer. My server has restricted internet access, so I didn't have the latest busybox, which was causing the min spec issue. I downloaded the images into a different server and [exported them](https://stackoverflow.com/questions/48125169/how-run-docker-images-without-connect-to-internet) into my server to get it working. – sykez Feb 04 '21 at 08:43
