Workshop preparation

AWS credentials

Checkout code from github

Create code commit repository

Push code to repository

Configure environment variables

export AWS_REGION=aws-region-code (eg. eu-west-1) export AWS_ACCOUNT_ID=your_account_id (eg. 1234567890) export CODECOMMIT_REPOSITORY_NAME=your_code_commit_repository_name (the one created above)

Bootstrap CDK with the right permissions

IMPORTANT : Please note we're giving Administrator access to keep it simple here, please scope down for real usage

cdk bootstrap --trust $AWS_ACCOUNT_ID --trust-for-lookup $AWS_ACCOUNT_ID --cloudformation-execution-policies 'arn:aws:iam::aws:policy/AdministratorAccess' aws://$AWS_ACCOUNT_ID/$AWS_REGION

Deploy preprod environement

Baseline stack

cd baseline/iac npm install cdk deploy -c envName=preprod

Infrastructure stack

cd infra/iac npm install cdk deploy -c envName=preprod

Initialize preprod database schema

EC2 instance with SSM

create database myservicepreprod create table items (id int not null auto_increment, name varchar(50) not null, price int not null, primary key (id));

API Pipeline

This creates a pipeline building the docker file and deploying to environments. By default, at this stage only preprod will be deployed. Prod stage is commented out in api-container-pipeline.ts, to be deployed in the prod section in the workshop.

cd api-container/iac npm install cdk deploy => please not no env here as it is a cross env pipeline

Check API is working

curl with public URL of API

Webapp

This creates a pipeline building the reactjs app and deploying to environments. By default, at this stage only preprod will be deployed. Prod stage is commented out in Webapp-pipeline.ts, to be deployed during prod section in the workshop.

cd webapp/iac npm install cdk deploy => please note no env here as it is a cross env pipeline

Check Webapp is working

Deploy production environement

Deploy prod stacks

cd baseline/iac npm install cdk deploy -c envName=preprod

cd infra/iac npm install cdk deploy -c envName=preprod

Initialize prod database schema

EC2 instance with SSM

create database myservicepreprod create table items (id int not null auto_increment, name varchar(50) not null, price int not null, primary key (id));

Add prod stage to API

and test

Add prod stage to Webapp

and test

Additional notes

public ecr

we're using public ecr instead of dockerhub

Gotchas

bucketdeployment when not changed delete assets buckets when it doesn't work redeploy bucket deployment stack pre doesn't work when you want to build but it is probably because of that ??

CDK Deploy-Step Fails - Lambda Assets not uploaded to S3 after build -- "Error occurred while GetObject. S3 Error Code: NoSuchKey" · Issue #11025 · aws/aws-cdk aws/aws-cdk#11025

local execution

it is possible to run DB and opensearch locally useting AWS_REGION and providing info on local tooling.

unset AWS_REGION export OS_LOCAL_USERNAME= export OS_LOCAL_PASSWORD= export DB_LOCAL_HOST= export DB_LOCAL_USERNAME= export DB_LOCAL_PASSWORD= export DATABASE_NAME= export OS_HOSTNAME= export OS_PORT=
