The redis server container, redis;5-alpine does not contain /bin/bash. As a result, the launch.sh script on page 13 fails. The fix is to change the script to #!/bin/sh

I have tried to run container I've just created from Dockerfile and I got an error

internal/modules/cjs/loader.js:638
throw err;
^

Error: Cannot find module 'redis'

How can I fix this issue? Why redis doesn't install despite on "RUN npm install -g redis" command within the Dockerfile?

I mean, in the book there's a bunch of samples, but this repo has only a few files in master branch and I can't see any other branch. Is this the correct repository for the book?

There's a lot of errors. :(

is this the repo for the book "Kubernetes Best Practices"? if so there are files missing, and according to the book the directory structure should be

journal/
    frontend/
    redis/
    fileserver/

missing files include ... redis Stateful set and Service yamls, launch script and maybe some others. also the frontend.yaml is missing the volumes and volumeMounts sections

The file frontend.yaml does not deploy successfully as it uses "request" rather than "requests" to specify resource utilisation. This is also reflected in the code displayed in the book.
