How to fix it?

CodePudding user response：

add springboot-docker dir to your $PATH variable.

basically the shell is not able to find the mvnw command, it looks for all the locations in the $PATH var. since your mvnw binary is located in your project dir you need to add it.

if this was in a linux environment it would be done like this export PATH=$PATH:./springboot-docker

for windows you can search online how this can be edited.

CodePudding user response：

Change CMD [ "mvnw", "spring-boot:run" ] to CMD [ "./mvnw", "spring-boot:run" ]

When your docker want to execute command mvnw springboot:run, it needs to find file mvnw in environment $PATH， but find none.

Change mvnw to ./mvnw which will tell docker to execute the mvnw file in current work directory(where you have copied mvnw before).
