I have setup drone.io locally and created a .drone.yml for CI build. But I found drone removes the docker container after finishing the build Whether it support reusing the docker container? I am working on gradle project and the initial build takes a long time to download java dependencies.

UPDATE1

I used below command to set the admin user on running drone-server container.

docker run -d
-e DRONE_GITHUB=true
-e DRONE_GITHUB_CLIENT="xxxx"
-e DRONE_GITHUB_SECRET="xxxx"
-e DRONE_SECRET="xxxx"
-e DRONE_OPEN=true
-e DRONE_DATABASE_DRIVER=mysql
-e DRONE_DATABASE_DATASOURCE="root:root@tcp(mysql:3306)/drone?parseTime=true"
-e DRONE_ADMIN="joeyzhao0113"
--restart=always
--name=drone-server
--link=mysql
drone/drone:0.5

After doing this, I use the user joeyzhao0113 to login drone server but failed to enable the Trusted flag on the setting page. The popup message dialog shows setting successfully see below screenshot. But the flag keep showing disabled always.

No, it is not possible to re-use a Docker container for your Drone build. Build containers are ephemeral and are destroyed at the end of every build.

That being said, it doesn't mean your problem cannot be solved.

I think a better way to phrase this question would be "how do I prevent my builds from having to re-download dependencies"? There are two solutions to this problem.
Option 1, Cache Plugin

The first, recommended solution, is to use a plugin to cache and restore your dependencies. Cache plugins such as the volume cache and s3 cache are community contributed plugins.

pipeline:
 # restores the cache from a local volume
 restore-cache:
   image: drillster/drone-volume-cache
   restore: true
   mount: [ /drone/.gradle, /drone/.m2 ]
   volumes: /tmp/cache:/cache

 build:
   image: maven
   environment:
     - M2_HOME=/drone/.m2
     - MAVEN_HOME=/drone/.m2
     - GRADLE_USER_HOME=/drone/.gradle
   commands:
     - mvn install
     - mvn package

 # rebuild the cache in case new dependencies were
 # downloaded during your build
 rebuild-cache:
   image: drillster/drone-volume-cache
   rebuild: true
   mount: [ /drone/.gradle, /drone/.m2 ]
   volumes: /tmp/cache:/cache

Option 2, Custom Image

The second solution is to create a Docker image with your dependencies, publish to DockerHub, and use this as your build image in your .drone.yml file.

pipeline:
build:
image: some-image-with-all-my-dependencies
commands:

 - mvn package



 the default workspace base is /drone assuming you didn't override the default base value. This means you can set GRADLE_USER_HOME=/drone/.gradle to instruct gradle to store the dependencies in your workspace, making accessible to the cache plugin. I've updated the example in my answer to show how this could work. – Brad Rydzewski
