# What is
- Aliases to handle finding and connecting to ec2 instances over SSM so you're not using ssh and you don't have to remember the syntax

# How use
- Add to your aliases (e.g. ~/.zshrc.local, ~/.bashrc, ~/.bash_profile, or in your full aliases section), source (new terminal session should do the trick!)

# Must haz
- Ok, here goes.

1. `ec2` - prompt that will allow you to enter a name or part of a name (ignores case) and return all hosts in the set of regions listed so you can grab the Instance ID and use it for whatever (including the later `ssm` command)
1.1. includes some basic info about the hosts, IP, ID, region, State, Size/type.
1.2. defaults to returning all hosts if none entered

```
ec2() {
    US_REGIONS=("us-east-1" "us-east-2" "us-west-1" "us-west-2")

    for REGION in "${US_REGIONS[@]}"; do
        echo "Region: $REGION"
        if [ -z "$1" ]; then
            aws --region "$REGION" ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId, Tags[?Key==`Name`].Value | [0], InstanceType, PublicIpAddress, PrivateIpAddress, State.Name]' --output table
        else
            aws --region "$REGION" ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId, Tags[?Key==`Name`].Value | [0], InstanceType, PublicIpAddress, PrivateIpAddress, State.Name]' --output table | grep -i "$1"
        fi
        echo
    done
}
```

2. `ssm` - prompt that you can take the instance ID and directly connect (note: default behavior with no input is similar to `ec2` above

```
ssm () {
    export AWS_PAGER=""

    if [ -z "$1" ]; then
        echo "No instance specified. Here are the available instances:"
        echo "----------------------------------------------------"
        ec2
        echo "----------------------------------------------------"
        echo "Usage: ssm <instance-id or name> [region]"
        echo "Example: ssm i-1234567890abcdef0"
        echo "         ssm webserver"
        echo "         ssm webserver us-west-2"
        return 1
    fi

    local instance_id=$1
    local region=${2:-us-east-2}
    
    # If the first argument doesn't start with "i-", treat it as an instance name
    if [[ ! "$instance_id" =~ ^i- ]]; then
        # Get the instance ID of the most recent instance matching the name (case insensitive)
        instance_id=$(aws --region "$region" ec2 describe-instances \
            --filters "Name=tag:Name,Values=*${instance_id}*" \
            --query 'sort_by(Reservations[].Instances[], &LaunchTime)[-1].InstanceId' \
            --output text)
        
        if [[ "$instance_id" == "None" || -z "$instance_id" ]]; then
            echo "No matching instance found with name containing: $1"
            return 1
        fi
        echo "Connecting to instance: $instance_id"
    fi
    
    aws --region "$region" ssm start-session --target "$instance_id"
}
```
