[Feature]: Add Command to Validate Generated Config

[chefgs]

Title

Add devopsos validate command to check generated configs

Description

Create a CLI command:

devopsos validate

It should check for:

Dockerfile syntax
GitHub Actions YAML
Kubernetes YAML

This helps developers verify generated configurations.

Hi @chefgs,

I would like to work on this issue.
I plan to implement the devopsos validate command to check Dockerfile syntax, GitHub Actions YAML, and Kubernetes YAML.

Please assign this issue to me.

Hello @vishnu-varthan1 ,
You can proceed assign this task to yourself.

Please briefly explain how your analysis and planning to implement this feature.

Hi @chefgs,

Thank you for the opportunity to work on this feature.
Analysis

The goal of the devopsos validate command is to verify the correctness of generated configuration files before developers use them. Based on the issue description, the command will validate the following:

1. Dockerfile syntax – ensure the Dockerfile follows valid Docker build syntax.
2. GitHub Actions workflow YAML – validate .github/workflows/*.yml files for correct YAML structure.
3. Kubernetes YAML manifests** – validate Kubernetes resource definitions (Deployment, Service, etc.).
   Implementation Plan

1.Add CLI Command

Extend the CLI to include:

devopsos validate

This command will trigger validation checks for all supported configuration files.

2. Dockerfile Validation

   Detect if a Dockerfile exists in the project directory.
   Use Docker build parsing or a lightweight syntax check (for example using docker build --dry-run or Dockerfile lint tools).

3. YAML Validation

   Parse YAML files using a YAML parser.
   Validate:
   github/workflows/*.yml Kubernetes manifest files (deployment.yaml, service.yaml`, etc.).
   Ensure proper YAML syntax and structure.

4. Error Reporting

   If an invalid configuration is detected, display a clear error message with the file name and issue.
   Example output:
   ✔ Dockerfile syntax valid
   ✖ kubernetes/deployment.yaml – YAML syntax error at line 12
   ✔ .github/workflows/ci.yml valid

5. Success Output

   If all checks pass:
   All configuration files are valid.

Next Steps

Explore the existing CLI structure in the repository.
Implement the validation logic in a modular way so additional validators can be added in the future.

Please let me know if you would like the validation to include additional checks such as linting or schema validation.

Thanks!
