Using the AWS Copilot command line interface - Amazon Elastic Container Service

Using the AWS Copilot command line interface

The AWS Copilot command line interface (CLI) commands simplify building, releasing, and operating production-ready containerized applications on Amazon ECS from a local development environment. The AWS Copilot CLI aligns with developer workflows that support modern application best practices: from using infrastructure as code to creating a CI/CD pipeline provisioned on behalf of a user. Use the AWS Copilot CLI as part of your everyday development and testing cycle as an alternative to the AWS Management Console.

AWS Copilot currently supports Linux, macOS, and Windows systems. For more information about the latest version of the AWS Copilot CLI, see Releases.

Note

The source code for the AWS Copilot CLI is available on GitHub. The latest CLI documentation is available on the AWS Copilot website. We recommend that you submit issues and pull requests for changes that you would like to have included. However, Amazon Web Services doesn't currently support running modified copies of AWS Copilot code. Report issues with AWS Copilot by connecting with us on Gitter or GitHub where you can open issues, provide feedback, and report bugs.

Installing the AWS Copilot CLI

The AWS Copilot CLI can be installed on Linux or macOS systems either by using Homebrew or by manually downloading the binary. Use the following steps with your preferred installation method.

Installing the AWS Copilot CLI using Homebrew

The following command is used to install the AWS Copilot CLI on your macOS or Linux system using Homebrew. Before installation, you should have Homebrew installed. For more information, see Homebrew.

brew install aws/tap/copilot-cli

Manually installing the AWS Copilot CLI

As an alternative to Homebrew, you can manually install the AWS Copilot CLI on your macOS or Linux system. Use the following command for your operating system to download the binary, apply execute permissions to it, and then verify it works by listing the help menu.

macOS

For macOS:

sudo curl -Lo /usr/local/bin/copilot https://github.com/aws/copilot-cli/releases/latest/download/copilot-darwin \ && sudo chmod +x /usr/local/bin/copilot \ && copilot --help

For macOS ARM systems:

sudo curl -Lo /usr/local/bin/copilot https://github.com/aws/copilot-cli/releases/latest/download/copilot-darwin-arm64 \ && sudo chmod +x /usr/local/bin/copilot \ && copilot --help
Linux

For Linux x86 (64-bit) systems:

sudo curl -Lo /usr/local/bin/copilot https://github.com/aws/copilot-cli/releases/latest/download/copilot-linux \ && sudo chmod +x /usr/local/bin/copilot \ && copilot --help

For Linux ARM systems:

sudo curl -Lo /usr/local/bin/copilot https://github.com/aws/copilot-cli/releases/latest/download/copilot-linux-arm64 \ && sudo chmod +x /usr/local/bin/copilot \ && copilot --help
Windows

Using Powershell, run the following command:

New-Item -Path 'C:\copilot' -ItemType directory; ` Invoke-WebRequest -OutFile 'C:\copilot\copilot.exe' https://github.com/aws/copilot-cli/releases/latest/download/copilot-windows.exe

(Optional) Verify the manually installed AWS Copilot CLI using PGP signatures

The AWS Copilot CLI executables are cryptographically signed using PGP signatures. The PGP signatures can be used to verify the validity of the AWS Copilot CLI executable. Use the following steps to verify the signatures using the GnuPG tool.

  1. Download and install GnuPG. For more information, see the GnuPG website.

    macOS

    We recommend using Homebrew. Install Homebrew using the instructions from their website. For more information, see Homebrew. After Homebrew is installed, use the following command from your macOS terminal.

    brew install gnupg
    Linux

    Install gpg using the package manager on your flavor of Linux.

    Windows

    Download the Windows simple installer from the GnuPG website and install as an Administrator. After you install GnuPG, close and reopen the Administrator PowerShell.

    For more information, see GnuPG Download.

  2. Verify the GnuPG path is added to your environment path.

    macOS
    echo $PATH

    If you do not see the GnuPG path in the output, run the following command to add it to the path.

    PATH=$PATH:<path to GnuPG executable files>
    Linux
    echo $PATH

    If you do not see the GnuPG path in the output, run the following command to add it to the path.

    export PATH=$PATH:<path to GnuPG executable files>
    Windows
    Write-Output $Env:PATH

    If you do not see the GnuPG path in the output, run the following command to add it to the path.

    $Env:PATH += ";<path to GnuPG executable files>"
  3. Create a local plain text file.

    macOS

    On the terminal, enter:

    touch <public_key_filename.txt>

    Open the file with TextEdit.

    Linux

    Create a text file in a text editor such as gedit. Save as public_key_filename.txt

    Windows

    Create a text file in a text editor such as Notepad. Save as public_key_filename.txt

  4. Add the following contents of the Amazon ECS PGP public key and save the file.

PGP PUBLIC KEY BLOCK-----

    The details of the Amazon ECS PGP public key for reference:

    Key ID: BCE9D9A42D51784F
    Type: RSA
    Size: 4096/4096
    Expires: Never
    User ID: Amazon ECS
    Key fingerprint: F34C 3DDA E729 26B0 79BE AEC6 BCE9 D9A4 2D51 784F

    You may close the text editor.

  5. Import the file with the Amazon ECS PGP public key with the following command in the terminal.

    gpg --import <public_key_filename.txt>
  6. Download the AWS Copilot CLI signatures. The signatures are ASCII detached PGP signatures stored in files with the extension .asc. The signatures file has the same name as its corresponding executable, with .asc appended.

    macOS

    For macOS systems, run the following command.

    sudo curl -Lo copilot.asc https://github.com/aws/copilot-cli/releases/latest/download/copilot-darwin.asc
    Linux

    For Linux x86 (64-bit) systems, run the following command.

    sudo curl -Lo copilot.asc https://github.com/aws/copilot-cli/releases/latest/download/copilot-linux.asc

    For Linux ARM systems, run the following command.

    sudo curl -Lo copilot.asc https://github.com/aws/copilot-cli/releases/latest/download/copilot-linux-arm64.asc
    Windows

    Using Powershell, run the following command.

    Invoke-WebRequest -OutFile 'C:\copilot\copilot.asc' https://github.com/aws/copilot-cli/releases/latest/download/copilot-windows.exe.asc
  7. Verify the signature with the following command.

    • For macOS and Linux systems:

      gpg --verify copilot.asc /usr/local/bin/copilot
    • For Windows systems:

      gpg --verify 'C:\copilot\copilot.asc' 'C:\copilot\copilot.exe'

    Expected output:

    gpg: Signature made Tue Apr  3 13:29:30 2018 PDT
    gpg:                using RSA key DE3CBD61ADAF8B8E
    gpg: Good signature from "Amazon ECS <ecs-security@amazon.com>" [unknown]
    gpg: WARNING: This key is not certified with a trusted signature!
    gpg:          There is no indication that the signature belongs to the owner.
    Primary key fingerprint: F34C 3DDA E729 26B0 79BE  AEC6 BCE9 D9A4 2D51 784F
         Subkey fingerprint: EB3D F841 E2C9 212A 2BD4  2232 DE3C BD61 ADAF 8B8E
    Important

    The warning in the output is expected and is not problematic. It occurs because there is not a chain of trust between your personal PGP key (if you have one) and the Amazon ECS PGP key. For more information, see Web of trust.

  8. For Windows installations, run the following command on Powershell to add AWS Copilot directory to the path.

    $Env:PATH += ";<path to Copilot executable files>"

Next steps

After installation, learn how to deploy an Amazon ECS application using AWS Copilot. For more information, see Getting started with Amazon ECS using AWS Copilot.
