AWS amplify don't deploy build infinit - amazon-web-services

I have a project to react to and I want to deploy it on AWS Amplify, locally I run the build perfectly, but when I do it on AWS it is compiling infinitely until I get a time out error. What am I doing wrong? I'm new to it and I couldn't find anything related

Running Storybook on amplify in a nextjs project

Im trying to run storybook from amplify in a nextjs project.
It sets the framework as Nextjs SSR but i went ahead and changed it to React and the app platform was kept as it is to Web Compute
I updated the amplify.yaml file as:
version: 1
frontend:
phases:
preBuild:
commands:
- nvm install
- nvm use
- yarn install --immutable
build:
commands:
- npm run build-storybook
artifacts:
baseDirectory: storybook-static
files:
- "**/*"
cache:
paths:
- node_modules/**/*
But the build always fails with this error

Looks like it still tries to find a nextjs app how to get the storybook running in a nextjs app on amplify ?

NextJS deployment on AWS amplify issue (frontend + incompatible module)

I deploy the nextjs project by connecting the github repo, the provision passes, the backend is built, but the frontend fails to build. Here is the log with the error:

The build settings:

commands:
- yarn install
build:
commands:
- yarn run build
artifacts:
baseDirectory: .next
files:
- '**/*'

I really do not know how to fix this, is it an AWS issue or my project has outdated packages? Any help would be appreciated 😄.
To fix this issue you have to tell Amplify which version of NodeJS to use.
Go To:
Build Settings
At the bottom is Edit Build image settings
Click Add Package Overide
Set your NodeJS version
This worked for me.

I figured out my issue! While developing locally, I was using a .env file. I had to add the environment variable to my build via through amplify. Documentation: https://docs.aws.amazon.com/amplify/latest/userguide/environment-variables.html#access-env-vars

Integrating SonarQube within AWS CodePipeline: Connection Refused

tl;dr
CodePipeline crashes on the mvn sonar:sonar line of my buildspec.yml file with the following log (I formatted it a bit for better readability):
[ERROR] SonarQube server [http://localhost:9000] can not be reached
...
[ERROR] Failed to execute goal
org.sonarsource.scanner.maven:sonar-maven-plugin:3.7.0.1746:sonar
(default-cli) on project myproject:
Unable to execute SonarQube:
Fail to get bootstrap index from server:
Failed to connect to localhost/127.0.0.1:9000:
Connection refused (Connection refused) -> [Help 1]
Goal
This is my first project with AWS, so sorry if I'm providing irrelevant informations.
I'm trying to deploy my backend API so that it's reachable by the public. Among other things, I want a CI/CD set up to automatically run tests and abort on failure or if a certain quality gate isn't passed. If everything went fine, then the new version should automatically be deployed online.
Current state
My pipeline automatically aborts when one of the tests fails, but that is about all I've gotten to properly do.
I've yet to figure out how to deploy (even manually) the API to be able to send requests to it. Maybe it's already done and I just don't know which URL to use, though.
Anyways, as it is, the CodePipeline crashes on the mvn sonar:sonar line of my buildspec.yml file.

The environment
(Sorry for the hidden infos: not being sure what should remain private, I went on the safe side. If you need any specific information, please let me know!)
I have an Elastic Beanstalk set up with the following properties:
I also have an EC2 instance up and running:
I also use a VPC.
What I've tried
I tried adding a bunch of entries into the inbound rules of my EC2's Security Group:
I started from 0.0.0.0/0 : 9000, to then try 127.0.0.1/32 : 9000, to finally try All traffic. None of it worked, so the problem seems to be somewhere else.
I also tried changing some properties of the sonar-project.properties file, namely sonar.web.host and sonar.host.url, to try to redirect where the SonarQube server is hosted (I thought maybe I was supposed to point it to the EC2's IPv4 Public IP address or its attached Public DNS (IPv4)), but somehow the failing build log keeps displaying the failure to connect on localhost:9000 when trying to contact the SonarQube server.
I've figured it out.
Somehow, SonarQube reports having started properly despite that not being true. Thus, when you see this log after having ran your sh ./sonar.sh start command:
[Container] 2019/12/18 21:25:49 Running command sh ./sonar.sh start
Starting SonarQube...
Started SonarQube.
It isn't necessarily true that SonarQube's local server has successfully started. One would have to go into the logs folder of the SonarQube installation folder and read the sonar.log file to figure out that something was actually wrong and that the server was stopped...
In my case, it reported an error that JDK11 was required to run the server. To solve that, I changed the java: openjdk8 line of my buildspec.yml to java: openjdk11.
Then, I had to figure out that now a new log file was available to be read: es.log. When printing that file in the console, it was revealed to me that the latest ElasticSearch version (which is used by the latest SonarQube server version) does not allow itself to be ran by a root user. Thus, I had to create a new user group and edit some configuration file to run the server with that user:
# Set up non-root user to run SonarQube
- groupadd sonar
- useradd -c "Sonar System User" -d $sonarPath/$sonarQube -g sonar -s /bin/bash sonar
- chown -R sonar:sonar $sonarPath/$sonarQube # recursively changing the folder's ownership
# Launch SonarQube server locally
- cd ./$sonarQube/bin/linux-x86-64
- sed -i 's/#RUN_AS_USER=/RUN_AS_USER=sonar/g' sonar.sh # enabling user execution of server
- sh ./sonar.sh start
Complete solution
This gives us the following working version of buildspec.yml :

How do I set up my build scripts in AWS Amplify? They run successfully locally and fail in the build process for AWS Amplify

I am running my build scripts locally with NPM and they complete successfully. However, I am hosting my website with AWS Amplify, have accepted the default build settings per their recommendation but the build always fails on the during the frontend build.
I've read through the documentation (https://aws.amazon.com/getting-started/tutorials/deploy-react-app-cicd-amplify/)
Here is my build script in package.json:

The AWS Amplify build should complete successfully, but it always fails.
I used the following to get my build on AWS amplify. Follow the order of these steps, try the next if you fail.
First of all its recommended to use the same package manager for your build that you use in your project. Anyways try these:
try deleting and re-installing node_modules .
try building the project with webpack version(3.1.0)/webpack-server-version(1)
try deleting and re-installing react-scripts.
