In order to have an SSH session with the servers from task 2 without using Session Manager, it is necessary to have a key pair in the region and pass its name to the deploy.sh script. If you don't have a key configured, use the script create_ssh_key.sh to generate one.

make gen-ssh-key

The script will create a SSH Key pair in the desired region that can be configured using environment variables

Environment variables can be used to pass parameters to the script

• AWS_REGION: Region to deploy the key pair - Default: 'eu-west-2'
• SSH_KEY_NAME: Name to use in Key creation - Default: 'code-key'

#Changing key name and AWS Region AWS_REGION='eu-west-1' SSH_KEY_NAME='other-key-name'./create_ssh_key.sh

This Project has a deploy.sh script, that will perform the following actions:

make deploy

Environment variables can be used to pass parameters to the script

• AWS_REGION: Region to deploy the solution - Default: 'eu-west-2'

• DB_INSTANCE_TYPE: Instance type to be used by RDS - Default: 'db.t3.micro'

• DEV_PUBLIC_IP - Default: Automatically gets public IP from Machine running deploy.sh

• INSTANCE_TYPE- Instance type to be used by servers from task 2 - Default: 't3.micro'

• OWNER: Stack Owner, value will be used in R53 Domain and S3 Bucket - Default: 'someone'

• DOMAIN_NAME: Domain that will be used to create the Bucket and HostedZone - Default: '${OWNER]-${AWS_REGION}-somechallenge.com'

• NETWORK_Name: Name of Stack containing core network resources - Default: 'network'

• COMPUTE_name: Name of Stack containing Compute resources - Default: 'compute'

• PERSISTENCE_Name: Name of Stack containing Persistence resources- Default: 'persistence'

• SSH_KEY_NAME: Name from SSH key - Default: none

• To get running Instances IP Address:

AWS_REGION='eu-west-2'
COMPUTE_name='compute'

aws ec2 describe-instances \
    --filters "Name=tag:aws:cloudformation:stack-name,Values=${COMPUTE_name}" \
    --region "${AWS_REGION}" | jq -r ".Reservations[].Instances[].PublicIpAddress"

The credentials for the database are created automatically by AWS and they are stored in SecretsManager, under the following secret name: Secret

Get Domain Name used to deploy HostedZone

• Get DB Credentials

AWS_REGION='eu-west-2'
aws secretsmanager get-secret-value --region "${AWS_REGION}" --secret-id Secret | jq -r ".SecretString"
