When using Alpine linux on a server or Alpine-based container deployment, what are some well known bugs or gotchas? Include one section for MUSL libc issues, and a section for other. I am aware of the DNS issue on Kubernetes, so include that one in the MUSL section.
MUSL libc Issues:
- DNS resolution failures in Kubernetes due to MUSL's resolver not supporting search domains properly. Workaround: Use CoreDNS or external DNS servers
- No support for NSS modules, affecting LDAP/NIS authentication
- Incomplete locale support causing string sorting/comparison issues
- Limited threading model can impact high-concurrency applications
- Some compiled binaries may fail due to glibc dependencies
- No support for dlopen() on static binaries
