• The version constraint used for 'readline-dev>=8.2.0-r0' may not be supported by apk in this syntax, leading to potential install failures. Consider verifying the accepted version constraint syntax for apk or pinning the exact version as recommended in Alpine Linux documentation.

RUN apk add --no-cache build-base=0.5-r3 "readline-dev>=8.2.0-r0"
