Chapter 4 build fails apk not found. about manning-smia HOT 3 CLOSED

I will take a look at it. But If that's the case we should remove the run apk from the dockerfile. (I'm not taking advantage of the benefits of that apk so it's safe to remove it) Changing the base image to 14 is not a good idea because you will be using Java 14 instead of 11.

Thank you. I switched to 11, but still encountered the apk error (updated pom.xml to 11 and dockerfile's FROM entries to openjdk:11-slim). From your output, I know you did not encounter the apk error so I'm not sure if this is unique to me. I also tried apt-get, but had the same errors.

FROM alpine:3.4 is only to handle the apk entry, I returned to using FROM openjdk:14-slim just before the ARG DEPENDENCY line. This ensures LicenseServiceApplication will be found in the classpath and so that Java can be found. That attached file contains the dockerfile details. The dockerfile build is successful, as was the docker run command. As you mentioned, if netcat-openbsd is not being used, it's probably better to not include it and save on download time.

Hi, you can also use the dockerfile located in the chapter4 folder. I just ran the command mvn clean package dockerfile:build and is working.

Thanks for letting me know. I will be updating the content of the chapter to remove the apk line from the code listings.
