POC 2 - Input Sample	1. Swagger API Spec

AWS Bedrock Model Access to one or more of the anthropic (cross-region) models is fine.

Custom Bedrock Policy for AWS IAM User

{
    Version = "2012-10-17"
    Statement = [
        {
            Effect = "Allow"
            Action = [
              "bedrock:InvokeModel",
              "bedrock:InvokeModelWithResponseStream",
              "bedrock:ListFoundationModels",
              "bedrock:GetFoundationModel"
            ]
            Resource = "*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "bedrock:GetInferenceProfile",
                "bedrock:ListInferenceProfiles",
            ],
            "Resource": [
                "arn:aws:bedrock:*:*:inference-profile/*",
                "arn:aws:bedrock:*:*:application-inference-profile/*"
            ]
        }
    ]
}

• Configure AWS profile into launched server, either by

  • setting AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY, in $HOME/.profile

  • Or stage $HOME/.aws/credentials

• Transfer Roost license file (.ral) into EC2 instance.

• Transfer roostgpt-installer executable into the EC2 instance

• Ensure Python3 & AWS CLI is installed on the instance to support troubleshooting.

Details of Roost Installer 

Bundled artifact in the Roost installer

RoostGPT can be executed locally for Unit Tests. However, it is recommended that the necessary language version and build tools, dependency have to be installed on EC2 (Linux).

Name	Purpose / Description	Location
roostgpt-linux	CLI executable for roostGPT	Bundled binary   Reference: v1.1.18/roostgpt-linux
roostenc-linux	Decryt/Encrypt binary for troubleshooting RoostGPT behaviour	Bundled in the roostgpt-installer (not available publicly)
license/license.ral	Roost License File	Bundled in the roostgpt-installer (not available publicly)
workspace/postman-api-test	Sample swagger API spec file and env to generate postman collection with tests	API Spec: weather,yaml  Reference: https://openweathermap.org/api
workspace/functional-test	Sample Functional Test project with env	Sample word document written by Roost Team - (not publicly available)

Installation Steps

Mount EBS Volume (optional, check if it is done already)

1. Verify that /var/tmp/Roost does not exist already
2. Check the read/write/execute permissions on the mount point
3.  Extract the volume ID
4. Mount the disk, volume as Roost folder
5. Add fstab entry for handling m/c reboot

# Verify if the Roost folder exists
df -h /var/tmp/Roost

# if not create directory
sudo mkdir $ROOST_DIR
sudo chown `id -u`:`id -g` ${ROOST_DIR}

# Check if volume and disk exists
# Typically this is the 
export DISK="nvme0n1" 
export EBS_VOLUME="/dev/nvme0n1" 
blkid | grep "${DISK}:"
lsblk | grep -w "${EBS_VOLUME}"

# Run below snippet to mount disk and add entry to fstab file 
    lsblk -f | grep -w "${DISK}" | grep "ext4"
    if [ $? -ne 0 ]; then
      sudo mkfs -t ext4 ${EBS_VOLUME}
    fi
    if [ ! -d "${ROOST_DIR}" ]; then
      sudo mkdir ${ROOST_DIR}
    fi
    sudo mount ${EBS_VOLUME} ${ROOST_DIR}
    mount | grep "$EBS_VOLUME"
    if [ $? -eq 0 ]; then
      sudo chown `id -u`:`id -g` ${ROOST_DIR}

      grep -v "${ROOST_DIR}" /etc/fstab  | sudo tee /etc/fstab.noroost
      # Plan for reboot
      epoch=$(date +%s)
      sudo cp /etc/fstab /etc/fstab.orig.${epoch}
      which blkid
      if [ $? -eq 0 ]; then
        uuid=$(blkid | grep "${EBS_VOLUME}:" | awk '{print $2}'|sed -e 's/"//g')
      fi
      if [ -z $uuid ]; then
        id=$(lsblk -f -o NAME,UUID | grep -w "${DISK}" | awk '{print $2}'|sed -e 's/"//g')
        uuid="UUID=${id}"
      fi
      if [ ! -z $uuid ]; then
        echo "${uuid}     ${ROOST_DIR}    ext4    defaults        0       2" | sudo tee -a /etc/fstab.noroost
        sudo cp /etc/fstab.noroost /etc/fstab
        sudo umount ${ROOST_DIR}
        sudo mount -a
        if [ $? -eq 0 ]; then
          mount | grep "$EBS_VOLUME"
          if [ $? -ne 0 ]; then
           sudo chown `id -u`:`id -g` ${ROOST_DIR}
          fi
        fi
      fi

Copy the installer and license file

1. Download Installer from Shared Google Drive <LOCATION SENT OVER EMAIL>
   • You have to download the RoostGPT installer (Roost License file will be bundled) from a shared Google Drive.
2. Transfer Installer using scp
3. Make Installer executable

# From your local machine, copy installer to Ubuntu instance
scp roostgpt-installer.sh ubuntu@<your-instance-ip>:~/

# Then SSH into your instance
ssh ubuntu@<your-instance-ip>


# Add execute permissions to installer
chmod +x roostgpt-installer.sh

# Execute Roost Installer
sudo ./roostgpt-installer.sh

Configure a new test

Each project folder in your workspace contains a <UNIQUE-TEST-NAME>.env file for configuration. You can copy this env and modify the contents for a new test run. Or create a new test env file.

Execute roostgpt with this new env.

# Create a new Roost Test Configuration File
vim new_test.env

Troubleshooting

Installation Issues

Problem: Permission denied when running installer

# Solution: Make sure you're using sudo
sudo ./roostgpt-installer.sh

Problem: Command not found: roostgpt

# Solution: Verify installation completed successfully
which roostgpt
# Should output: /usr/local/bin/roostgpt

# Check executable permissions on roostgpt and grant if missing
chmod +x $(which roostgpt)

# If not found, re-run the installer
sudo ./roostgpt-installer.sh

Problem: Insufficient disk space

# Solution: Check available space
df -h $HOME /var/tmp/Roost

# Free up space or use an instance with more storage

Runtime Issues

Problem: Can't find workspace

# Solution: Workspace is in your home directory
cd ~/workspace
ls -la

Problem: Configuration not loading

# Solution: Ensure .env files exist and are readable
find ~/workspace/ -name '*.env' -ls
find ~/workspace/ -name '*.env' -exec chmod 644 {} \;
