OCP IPI AWS Cheat Sheet

Set variables for AWS commands

• First I move my metadata.json to
• Either add to script and source, or add to bashrc and export

metadata=~/.metadata.json

source <(jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" $metadata)
region=$(jq -r ".aws.region" $metadata )
identifier=$(jq -r ".aws.identifier[0] | keys | flatten[]" $metadata)
vpcID=$(aws ec2 describe-vpcs --region ${region}  --filter "Name=tag:Name,Values=$infraID-vpc" --query "Vpcs[0].VpcId")

subnetID=$(aws ec2 describe-subnets --region ${region}   --filter "Name=vpc-id,Values=$vpcID" --filter "Name=tag:Name,Values=$infraID-public-*" --query "Subnets[1].SubnetId")

imageID=`aws ec2 describe-instances --region ${region}  --filters "Name=tag:Name,Values=*$infraID*" --query 'Reservations[1].Instances[*].[ImageId]' --output text`

• Function that can be used for quick ec2 describe* commands

  function awsocp {
    metadata=~/.metadata.json
    region=$(jq -r ".aws.region" $metadata)
    source <(jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" $metadata)
    aws ec2 describe-${@} --region ${region} --filters "Name=tag:Name,Values=$infraID-*"
   }

Using bashrc function from above

awsocp volumes
awsocp subnets 
awsocp images
awsocp route-tables
awsocp security-groups
