London startups use Bash for lightweight automation—container entrypoints, simple deployment scripts, and CI job steps—because it’s reliable and fast to iterate. Teams often combine Bash with Docker and Kubernetes, using scripts to bootstrap containers, manage build artifacts, or run migrations. Best practice is to encapsulate complexity: keep Bash for orchestration and call more expressive languages for data manipulation. In startup contexts, emphasize testability and reproducibility: run scripts in CI, avoid hard-coded credentials, and document assumptions. Community-wise: swap examples of concise bootstrap scripts, and discuss how teams balance speed-of-development with maintainability when using Bash in product environments.
