The latest docker image is crashing with docker version 19.03.12 with the message below, I am using docker-compose to bring the container up.

Recreating my_element-alerts ... done
Attaching to my_element-alerts
my_element-alerts | `/root` is not writable.
my_element-alerts | Bundler will use `/tmp/bundler20211029-1-ut6rzs1' as your home directory temporarily.
my_element-alerts | bundler: command not found: rackup
my_element-alerts | Install missing gem executables with `bundle install`

Accordingly to the thread on link below it is a issue between older docker version before 20.10 + ruby alpine 3.0.

• https://issueexplorer.com/issue/docker-library/ruby/351

I changed the alpine version to 3.13 and it solves the error, see the diff below:

diff --git a/Dockerfile b/Dockerfile
index 3184eb6..6e12766 100644
--- a/Dockerfile
+++ b/Dockerfile
@@ -1,4 +1,4 @@
-FROM ruby:3.0-alpine
+FROM ruby:alpine3.13
 
 #RUN apt-get update -qq && apt-get install -y build-essential

Maybe this breaks other contexts, but for my environment it fixed the errors /root is not writable.

By the way, thanks @ananace for this great tool!
