The mongo image's Dockerfile has two directories named in a VOLUME statement. You're mounting content on /data/db but not on /data/configdb.

If the Dockerfile declares a directory as a VOLUME and nothing is explicitly mounted there, Docker automatically creates an anonymous volume (your first case). That's what results in the additional volume appearing in the docker volume ls listing.

The error spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'template', and 'updateStrategy' are forbidden saying it all.

In StatefultSet only mutable (you can change/update) is replicas, template, and updateStrategy. Other than these fields in Spec you cannot change others fields during updates.

You have multiple issues:

1. in the StatefuleSet Spec you used serviceName: auth-mongo-ss, do you have this headless service?

2. In this service spec you did not give selector

If you see your Dockerfile, you have specified base image as python:3.7.

If you visit the dockerfile of the base image python:3.7 here, you can see that basically you are installing a debian os and then python.To be more clear,If the image name is python:3.7, you get a docker image of debain with python 3.7 installed.

Now if you want to install ubuntu, you can set the base image as ubuntu:[tag] and then install each dependencies (python 3.7 , django,postgresql,reactsjs).

You can view this article which will help you to decide base docker image for your use case.

Connections between containers ignore ports:. Use the standard port for the target container, in this case the standard MongoDB port 27017.

django.contrib.sessions is not a callable object, hence it's not a valid context processor.

In fact, it's an app and, so, it should be in your INSTALLED_APPS list, not in the TEMPALTES context_processors list. Removing it from there should fix this issue.

Why is this happening?

The exception mentions that it is happening in django/template/context.py line 246 (in Django v3.0.11). If you see the source code at line 246, you can see that at this line Django is running the registered template context processors. Since, django.contrib.sessions is not a callable object, but a module, you get this exception message: 'module' object is not callable.

you're correct that you need to cd, but you'll need to do that inside of docker

for example:

You will need to replace "localhost" with the url of the deployed back-end.

React is a client-side javascript library, and runs in the users web browser, so it will use the "localhost" of the user that visits your page, not the server's localhost.

The reason why it failed because the dependencies used by golang program are not available inside docker for it to build successfully.

You are using dep for dependency management i.e. for your external libraries locally but have not installed any of them in the docker.

You need to have them available in docker by having first dep tool within your container. The dep tool will ensure that your dependencies required by the package are available by dep ensure

Also, you should ideally put your repository in the $GOPATH as mentioned below

The dockerfile will need these commands:

When mounting a path you can attach Mounts to the HostConfig like this:
