Codefresh – The Best CI/CD Platform With GitOps

Codefresh is a continuous integration and delivery (CI/CD) platform specifically designed to support the development and deployment of cloud-native applications.

Codefresh allows developers to automate the process of integration, testing, and deployment, making it easier to ensure consistent, high-quality releases. It comes with a built-in Docker registry and Helm repository, which allows you to manage all aspects of your Docker images and Helm charts in one place.

By combining a Docker-native CI/CD pipeline with a private Docker registry and Helm repository, Codefresh provides a comprehensive toolset for organizations that are migrating to microservices architectures using Docker and Kubernetes.

Built specifically with Docker and Kubernetes in mind, Codefresh provides a robust platform that is designed to simplify the process of building, testing, and deploying Docker containers within your software development life cycle.

For a seamless CI/CD experience, Codefresh offers native integrations with almost every major Git or Cloud provider. It allows for easy connections with Git providers, registry providers, storage providers, secret stores, and notification channels. This makes for a more streamlined and efficient CI/CD process by reducing the need for third-party plugins or workarounds.

Features

Codefresh has several key features:

• Docker Native: Codefresh was built with Docker in mind from the beginning. It can build, test, and push Docker images to any Docker registry.
• Kubernetes Deployment: Codefresh has first-class support for Kubernetes, making it easier to deploy and manage applications on Kubernetes clusters.
• Git Integration: Codefresh integrates with several popular Git hosting providers like GitHub, GitLab, and Bitbucket. It can automatically trigger pipelines based on Git events such as commits and pull requests.
• Pipelines: Codefresh uses pipelines to define the steps needed to build, test, and deploy your application. Pipelines are defined using YAML, a human-readable data serialization language.
• Helm Chart Support: Codefresh supports Helm, a package manager for Kubernetes. This simplifies the process of deploying and managing applications on Kubernetes.
• Monitoring and Logging: Codefresh provides built-in monitoring and logging capabilities to help you troubleshoot issues with your applications and pipelines.

Codefresh CLI

The Codefresh CLI is a tool that allows users to interact with the Codefresh platform directly from their command line or terminal. This tool provides a robust and flexible way to access and control Codefresh's features and functionality, without the need to use the web interface.

Users can perform a variety of tasks with the CLI such as creating, managing, and running pipelines, managing resources, and much more. It's designed to support complex automation scenarios and can also be used within pipeline steps for more advanced use cases.

In summary, Codefresh CLI is a powerful tool for developers who want to have more control and flexibility when working with the Codefresh platform.

Install Codefresh CLI in Linux

There are several methods to install the Codefresh CLI:

3. Direct Install

Download the latest version of Codefresh CLI from the codefresh official releases page. You can do this using wget command like below:

$ wget https://github.com/codefresh-io/cli/releases/download/v0.84.2/codefresh-v0.84.2-linux-x64.tar.gz

After the download is complete, you'll need to extract the binary from the tar.gz file. Use the tar command for this:

$ tar -zxvf codefresh-v0.84.2-linux-x64.tar.gz

Once extracted, you'll have a binary file named codefresh. To make this command easily accessible, move it to a directory in your PATH. A common choice is /usr/local/bin/:

$ sudo mv codefresh /usr/local/bin/

Verify that the command is available by running:

$ codefresh version
client version: 0.84.2

With these steps, you should now have Codefresh CLI installed on your Linux system and be able to use it from any location in your terminal.

4. Install Codefresh CLI Using Docker

First, ensure Docker is installed on your system. If not, follow the instructions on our Docker installation guide to install Docker in Ubuntu.

Once Docker is installed, you can pull the latest version of the Codefresh CLI image from Docker Hub using the following command:

$ docker pull codefresh/cli

If you want to pull a specific version of the Codefresh CLI image, replace ${VERSION} with the version number you want and run:

$ docker pull codefresh/cli:${VERSION}

After pulling the image, you can run the Codefresh CLI in a Docker container using the following command:

$ docker run codefresh/cli codefresh version

If you pulled a specific version, use the following command to run it:

$ docker run codefresh/cli:${VERSION} codefresh version

Configure Codefresh Completion

Codefresh needs a shell to be associated with it. So once the Codefresh is installed, it has to be associated with a selective shell and in this case it is "bash".

$ codefresh completion bash

Sample output:

###-begin-codefresh-completions-###
#
# codefresh command completion script
#
# Installation: codefresh completion >> ~/.bashrc
#    or codefresh completion >> ~/.bash_profile on OSX.
#
_codefresh_completions()
{
    local cur args type_list

    cur="${COMP_WORDS[COMP_CWORD]}"
    args=("${COMP_WORDS[@]}")

    # ask codefresh to generate completions.
    type_list=$(codefresh --get-yargs-completions "${args[@]}")

    if [[ ${type_list} == '__files_completion__' ]]; then
        _filedir "@(yaml|yml|json)"
    else
        COMPREPLY=( $(compgen -W "${type_list}" -- ${cur}) )
    fi

    return 0
}
complete -F _codefresh_completions codefresh
###-end-codefresh-completions-###

Generating the Codefresh API key

The API key required for authentication can be generated using the Codefresh web interface.

1. Start by creating a Codefresh account using your Gmail or Github ID. After creating your account, log in to Codefresh.

2. Navigate to the "User Settings" page.

3. On the "User Settings" page, go to the "API Keys" section and click GENERATE button.

4. Enter a key name of your choice, for example, "ostechnix_codefresh". Select the required scopes ("read", "write") for each category, and then click on the "CREATE" button. A "Token was generated" message will appear. Click on "Copy token to clipboard" option to copy the generated key.

Once the API key is generated, it can be used for authenticating with Codefresh via the command line.

Codefresh offers a comprehensive API which you can use it to integrate with any other application or solution you already have.

Setting up Authentication for Codefresh CLI

After successfully installing and configuring Codefresh, the next step involves setting up authentication for future applications you wish to integrate.

Checking existing authentication contexts:

Start by checking if there are any existing authentication contexts using the command:

$ codefresh auth get-contexts 

If there are no pre-existing contexts, the output will be:

No authentication contexts. Please create an authentication context (see codefresh auth create-context --help)

Creating a new authentication context:

Since we don't have any existing authentication contexts, we'll need to create a new one. Authentication contexts allow you to work with multiple accounts.

Create a new context using the command:

$ codefresh auth create-context --api-key <xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> 

Replace "xxxxxxxxxxxxxxxxxxxxxxxxx" with your actual key that you've created earlier.

Once this command is executed, Codefresh CLI will be fully authenticated. The API key will generally be stored in the ~/.cfconfig file. This command only needs to be run once, and it allows for the management of multiple authentications with different Codefresh accounts.

You can verify the existing authentication contexts using the command:

$ codefresh auth get-contexts 

Sample Output:

CURRENT NAME    URL                    ACCOUNT   STATUS
*       default https://g.codefresh.io ostechnix Valid 

And that's it! Your Codefresh CLI should now be ready for action, fully authenticated and equipped to work with multiple accounts.

For usage details, refer the Codefresh help section by entering the following command:

$ codefresh --help

You can also read official documentation provided at the end.
