Cohesity Cloud Scale Technology Deployment Guide Using Terraform for AWS

Installing packages on Terraform Management Server

1. Install Docker

   Follow these steps to allow non-root user to access and leverage Docker.

   a. Create and APT keyring directory using commands:

   mkdir /etc/apt/keyrings

   chmod 755 /etc/apt/keyrings

   b. Download the docker.gpg file and place in the keyring folder:

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg

   c. Download the Docker repository. Ensure that the below command is to be pasted as single shell. It only takes a second to run.

   echo deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable | tee /etc/apt/sources.list.d/docker.list

   d. Install the Docker files using the next two commands one by one.

   apt update

2. apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

   e. Confirm that Docker is installed correctly.

   docker run hello-world

3. Install Terraform package

   a. Install the unzip using the command:sudo apt-get install unzip

   b. Confirm the latest version on the Terraform website: https://www.terraform.io/downloads.html

   c. Download the latest version of the Terraform. Substitute the new version number if needed:

   wget https://releases.hashicorp.com/terraform/<latest_version>/terraform_<latest_version>_linux_amd64.zip

   d. Extract the downloaded file archive:

   unzip terraform_<latest_version>_linux_amd64.zip

   e. Move the executable into a directory using the command: sudo mv terraform /usr/local/bin/

   f. Execute the Terraform using the command: terraform --version

4. Install Kubectl using root user

   a. Download the kubectl binary.

   curl -LO https://dl.k8s.io/release/v1.25.0/bin/linux/amd64/kubectl

   b. Install the kubectl binary into /usr/local/bin

   install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

5. Install Helm package manager

   a. Download the binary file:

   curl -sSL https://get.helm.sh/helm-vx.xx.x-linux-amd64.tar.gz -o helm-vx.xx.x-linux-amd64.tar.gz

   b. Unarchive the Helm binary file.

   tar xvf helm-vx.xx.x-linux-amd64.tar.gz

   c. Copy the binary into /usr/local/bin

   cp linux-amd64/helm /usr/local/bin/helm

   chmod 775 /usr/local/bin/helm

6. Install the AWS command line interface

   a. Download the latest version of AWS CLI bundle

   curl -sSL https://awscli.amazonaws.com/awscli-exe-linux-x86_64-<latest_version>.zip -o awscli-exe-linux-x86_64-<latest_version>.zip

   b. Unzip the bundle (LOTS of files in this unzip)

   unzip awscli-exe-linux-x86_64-<latest_version>.zip

   c. Execute the installation script:

   ./aws/install

7. Copy over the Veritas binary file bundle and Terraform script bundle. This is a large file which may take sometime.
8. Unzip the file downloaded on the location:

   • Ubuntu: /home/ubuntu

   • RHEL: /home/ec2-user
