Also, you might be using tools like Maven or Gradle to help build the app.
#Container image tool code
When building Java-based applications, a JDK is needed to compile the source code to Java bytecode. Reduce overall image size by shipping only what your app needs to run.Separate build-time dependencies from runtime dependencies.Tool to help use multiple stages to create an image. While we’re not going to dive into it too much in this tutorial, multi-stage builds are an incredibly powerful Pushing and pulling this image and updates to it => => writing image sha256:91790c87bcb096a83c2bd4eb512bc8b134c757cda0bdee4038187f98148e2edaįirst off, you should notice that the build was MUCH faster! And, you’ll see that several steps are using previously cached layers. This time, your output should look a little different. Now, make a change to the src/static/index.html file (like change the to say “The Awesome Todo App”).īuild the Docker image now using docker build -t getting-started.

If you add the -no-trunc flag, you’ll get theįull output (yes. You’ll notice that several of the lines are truncated.
