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.

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-###

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> 
Create New Authentication Context
Create New Authentication Context

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.
