 You will need to generate your locale if you would like to use a specific one for your glibc application. You can do this by installing the `glibc-i18n` package and generating a locale using the `localedef` binary. An example for en_US.UTF-8 would be:
 
-    apk add glibc-bin-2.28-r0.apk glibc-i18n-2.28-r0.apk
+    apk add glibc-bin-2.29-r0.apk glibc-i18n-2.29-r0.apk
