= Deploying a Java application using a devile

In this section, you will learn how to deploy a sample Java project that uses Maven and Java 8 JDK using a devfile.

.Procedure

. Create a directory to store the source code of your component:
+
----
 $ mkdir <directory-name>
----

. Create a component configuration of Spring Boot component type named `myspring` and download its sample project:
+
----
   $ odo create java-spring-boot myspring --downloadSource
----
+
The previous command produces the following output:
+
----
   Experimental mode is enabled, use at your own risk

   Validation
    ✓  Checking devfile compatibility [195728ns]
    ✓  Creating a devfile component from registry: DefaultDevfileRegistry [170275ns]
    ✓  Validating devfile component [281940ns]

    Please use `odo push` command to create the component with source deployed
----
+
The `odo create` command downloads the associated `devfile.yaml` file from the recorded devfile registries.

. List the contents of the directory to confirm that the devfile and the sample Java application were downloaded:
+
----
  $ ls
----
+
The previous command produces the following output:
+
----
  README.md    devfile.yaml    pom.xml        src
----

. Create a URL to access the deployed component:
+
----
 $ odo url create --host apps-crc.testing
----
+
The previous command produces the following output:
+
----
  ✓  URL myspring-8080.apps-crc.testing created for component: myspring

 To apply the URL configuration changes, please use odo push
----
+
NOTE: You must use your cluster host domain name when creating the URL.

. Push the component to the cluster:
+
----
  $ odo push
----
+
The previous command produces the following output:
+
----
  Validation
   ✓  Validating the devfile [81808ns]

  Creating Kubernetes resources for component myspring
   ✓  Waiting for component to start [5s]

  Applying URL changes
   ✓  URL myspring-8080: http://myspring-8080.apps-crc.testing created

  Syncing to component myspring
   ✓  Checking files for pushing [2ms]
   ✓  Syncing files to the component [1s]

  Executing devfile commands for component myspring
   ✓  Executing devbuild command "/artifacts/bin/build-container-full.sh" [1m]
   ✓  Executing devrun command "/artifacts/bin/start-server.sh" [2s]

  Pushing devfile component myspring
   ✓  Changes successfully pushed to component
----

. List the URLs of the component to verify that the component was pushed successfully:
+
----
 $ odo url list
----
+
The previous command produces the following output:
+
----
 Found the following URLs for component myspring
 NAME              URL                                       PORT     SECURE
 myspring-8080     http://myspring-8080.apps-crc.testing     8080     false
----

. View your deployed application by using the generated URL:
+
----
  $ curl http://myspring-8080.apps-crc.testing
