This is a library for implementing 'serverless-like' sidecar services to existing, monolithic application's.
The target audience for this library are developers who must integrate CLIs to an existing application but don't want or can't add those CLIs to their existing container images.
A reasons for this may be that your software already has a large container image and you don't want to bloat it further. By using sidecar containers you keep your original image at the same size and you you can more flexibly upgrade the sidecar or you main application. Think upgrading your base Linux distro and then having lots of unexpected package version changes which may or may not lead to issues.
- You have some existing application which requires a CLI like
tesseract - You create a new Go project which imports this library and wraps the CLI
- You then create a new
Dockerfilewhich essentially contains only thetesseractCLI and your compiled Go program - This image can be integrated into your existing application's stack.
