- [Dockerfile: Use Absolute Paths for WORKDIR](https://protsenko.dev/infrastructure-security/workdir-path-not-absolute/): Relative WORKDIR values can produce ambiguous paths across layers\. Use absolute WORKDIR paths for clear and repeatable Docker builds\.
- [Dockerfile: Use '\-l' Flag with useradd to Prevent High UID Issues](https://protsenko.dev/infrastructure-security/useradd-missing-l-flag-high-uid/): Using useradd without \-l can create unexpected UID behavior and larger images\. Add \-l and keep user creation explicit for predictable container ownership\.
- [Dockerfile: Use WORKDIR Instead of 'RUN cd …'](https://protsenko.dev/infrastructure-security/use-workdir-over-cd/): Using RUN cd in Dockerfiles is fragile and harder to read\. Set WORKDIR once and run commands relative to that directory for predictable builds\.
- [Dockerfile: Use Package Manager Auto\-Confirm Flag '\-y'](https://protsenko.dev/infrastructure-security/use-package-manager-auto-confirm/): Missing \-y in package installs can stall non\-interactive builds\. Add explicit auto\-confirm flags to keep CI and Docker builds deterministic\.
- [Dockerfile: Standardise Remote GET Tools](https://protsenko.dev/infrastructure-security/standardise-remote-get/): Mixing curl and wget in one Dockerfile adds unnecessary packages and inconsistency\. Standardize one download tool and validate remote artifacts\.
