Setup AWS CLI and clone the workshop repo

For this workshop, please ignore warnings about the version of pip being used.

  1. Run the following command to view the current version of aws-cli:

    aws --version
    
  2. Update to the latest version:

    curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
    unzip awscliv2.zip
    sudo ./aws/install
    . ~/.bash_profile
    
  3. Confirm you have a newer version:

    aws --version
    

Install dependencies for use in the workshop by running:

sudo yum -y install jq gettext

Clone the GitHub repo

In order to execute the steps in the workshop, you’ll need to clone the workshop GitHub repo.

In the Cloud9 IDE terminal, run the following command:

git clone https://github.com/awslabs/ec2-spot-workshops.git

Change into the workshop directory:

cd ec2-spot-workshops/workshops/ecs-spot-capacity-providers

Feel free to browse around. You can also browse the directory structure in the Environment tab on the left and even edit files directly there by double clicking on them.

We should configure our aws cli with our current region as default:

export ACCOUNT_ID=$(aws sts get-caller-identity  --output text --query Account)
export AWS_REGION=$(curl -s  169.254.169.254/latest/dynamic/instance-identity/document | jq -r '.region')
echo "export  ACCOUNT_ID=${ACCOUNT_ID}" >> ~/.bash_profile
echo "export  AWS_REGION=${AWS_REGION}" >> ~/.bash_profile
aws configure set default.region ${AWS_REGION}
aws configure get default.region

Use the commands below to set the CloudFormation stack name to an environment variable.

Select the tab and follow the specific instructions depending on whether..

Provide the stack name you created earlier

export STACK_NAME=EcsSpotWorkshop

Get the stack name that was deployed already

export STACK_NAME=$(aws cloudformation list-stacks | jq -r '.StackSummaries[] | select(.StackName|test("mod.")) | .StackName')
echo "STACK_NAME=$STACK_NAME"

The output should look something like below.

STACK_NAME=mod-9feefdd1672c4eac

Run the command below to load CloudFormation outputs as the environment variables.

for output in $(aws cloudformation describe-stacks --stack-name ${STACK_NAME} --query 'Stacks[].Outputs[].OutputKey' --output text)
do
    export $output=$(aws cloudformation describe-stacks --stack-name ${STACK_NAME} --query 'Stacks[].Outputs[?OutputKey==`'$output'`].OutputValue' --output text)
    eval "echo $output : \"\$$output\""
done

Congratulations, your Cloud9 workspace setup is complete, and you can continue with this workshop.
