What frameworks do you know?

I am familiar with a number of frameworks and tools actively used in DevOps culture:

• For infrastructure automation:

  • Ansible
  • Terraform

• For building CI/CD pipelines:

  • Jenkins
  • GitLab CI
  • GitHub Actions

• For monitoring and logging:

  • Prometheus / Grafana
  • ELK Stack (Elasticsearch, Logstash, Kibana)

• For working with containers:

  • Docker Compose
  • Kubernetes Operators (although these are more extensions than frameworks in their pure form)

• For configuration management (though orchestration is more common now):

  • Chef
  • Puppet

Here's an example of using Terraform:

// Creating an AWS EC2 instance resource
resource "aws_instance" "example" {
  ami           = "ami-0abcdef1234567890"  // AMI image ID
  instance_type = "t2.micro"              // Instance type
  tags = {
    Name = "ExampleInstance"             // Adding a tag for identification
  }
}

And an example of a task in GitLab CI:

// Describing build and test stages in .gitlab-ci.yml
stages:
  - build
  - test

build_job:
  stage: build
  script:
    - echo "Building the project..."
    - make build

test_job:
  stage: test
  script:
    - echo "Running tests..."
    - make test
  needs:
    - build_job // Dependency on the previous stage

Each of these frameworks has its strengths and is used depending on the specific tasks and project features. My experience allows me to select and combine them to build effective and reliable DevOps processes.
