Here is a cheat sheet of common DevOps tools and commands with examples:

Tools

• Git: A version control system for tracking changes to files.
• Docker: A containerization platform for building and running applications in isolated environments.
• Kubernetes: An orchestration platform for managing containerized applications.
• Terraform: An infrastructure as code (IaC) tool for automating the provisioning and management of infrastructure resources.
• Ansible: A configuration management tool for automating the configuration of servers and other systems.
• Jenkins: A continuous integration (CI) and continuous delivery (CD) tool for automating the building, testing, and deployment of software.

Commands

• git clone <url>: Clone a remote Git repository to your local machine.
• git checkout <branch>: Switch to a different branch in Git.
• git push <remote> <branch>: Push the local branch to the remote repository.
• git pull <remote> <branch>: Pull the remote branch to the local repository.
• docker build -t <image name> <directory>: Build a Docker image from a directory.
• docker run -d -p <port>:<port> <image name>: Run a Docker image in detached mode, publishing the specified port to the host.
• kubectl get pods: List all Kubernetes pods.
• kubectl apply -f <file name>: Apply a Kubernetes manifest file.
• terraform init: Initialize Terraform.
• terraform plan: Show the changes that Terraform would make to the infrastructure.
• terraform apply: Apply the changes planned by Terraform.
• ansible-playbook <playbook name>.yml: Run an Ansible playbook.
• jenkins job build: Build a Jenkins job.

Example:

To build a Docker image from a directory and run it in detached mode, publishing port 80 to the host:

docker build -t my-image .
docker run -d -p 80:80 my-image

To apply a Kubernetes manifest file:

kubectl apply -f my-deployment.yml

To initialize Terraform and plan the changes that would be made to the infrastructure:

terraform init
terraform plan

To apply the changes planned by Terraform:

terraform apply

To run an Ansible playbook:

ansible-playbook my-playbook.yml

To build a Jenkins job:

jenkins job build
