To install packages in a docker container, the packages should be defined in the Dockerfile. If you want to install packages in the Container, use the RUN statement followed by exact download command. $ RUN pip install //IN Windows $ RUN apt-get install //in Ubuntu $ RUN yum install //CentOS/RHEL. Mac & Windows: install the Docker Toolbox to get Docker installed. As the generated files are in your shared folder, they will not be deleted if you stop your Docker container. However, if you don’t want Docker to keep downloading all the Maven and NPM dependencies every time you start the container, you should commit its state or mount a volume.

Docker Java Example

We shall learn following items in this Docker Java Example :

Apr 03, 2018 If you want to have kafka-docker automatically create topics in Kafka during creation, a KAFKACREATETOPICS environment variable can be added in docker-compose.yml. Here is an example snippet from docker-compose.yml: environment: KAFKACREATETOPICS: 'Topic1:1:3,Topic2:1:1:compact'. Topic 1 will have 1 partition and 3 replicas, Topic 2 will. Install Kafka In Docker Container; Install Kafka In Docker Windows 10; For local development and testing, you can run Pulsar in standalone mode on your own machine within a Docker container. If you have not installed Docker, download the Community edition and follow the instructions for your OS. Kafka writes data to a scalable disk structure. To start an Apache Kafka server, first, we'd need to start a Zookeeper server. We can configure this dependency in a docker-compose.yml file, which will ensure that the Zookeeper server always starts before the Kafka server and stops after it. Let's create a simple docker-compose.yml file with two services — namely, zookeeper and kafka.

Build Docker Image with Java Application

1. Create a directory

A separate directory is useful to organise docker applications. For this Java Example, create a directory somewhere with name of your choice. We shall use the name java-application

2. Create Java Application

Create a simple Java File, in the directory java-application, with name HelloWorld.java containing the following content.

3. Dockerfile

Create a file with name Dockerfile. Dockerfile contains instructions to prepare Docker image with our Java Application.

Following is the content of Dockerfile.

4. Verify contents of java-application directory

5. Build docker image

Install

Login as root user. Navigate into java-application directory and run the following command. Instructions in the Dockerfile are executed.

Install kafka in docker container

Please observe that there is dot (.) at the end of the command. Docker image is successfully built.

6. Check the docker image

To display available docker images, run the following command.

Run Docker Java Example

Run the following command to run the java-application Docker image in a container.

The Java Application has run, and the print statement could be seen in the console.

Save Docker Image to a tar file

Save the Docker Image file to a tar file, so that the image file could be copied to other machines through disk storage devices like pen-drive, etc.

Install Kafka And Zookeeper In Dockerfile

Run the following command to save Docker image as a tar file.

Saving might take few seconds. Wait for the command to complete.

Copy and Run the Docker Image file in another machine

Install Kafka On Docker Windows 10

You may copy the Docker image tar file to another computer.

Run the following command to load the Docker image into the Docker.

Kafka install docker free

Replace /home/arjun/workspace/java-application.tar with your file location.

You may run the image using the same command we used to run the image file after building.
