I am setting up Kafka and zookeeper through docker; however, my whenever I build my image I keep getting a code 8 error when it gets to:
wget -q https://www.apache.org/dist/zookeeper/zookeeper-${ZOOKEEPER_VERSION}/zookeeper-${ZOOKEEPER_VERSION}.tar.gz.asc .
I have tried to change the file format in the download-kafka.sh to unix already.

Exit Code 1 Indicates that the container stopped due to either an application error or an incorrect reference in Dockerfile to a file that is not present in the container.
'docker-compose up' is a Docker command to start and run an entire app on a standalone host that contains multiple services, for example, Web, DB, etc. It can also create volumes and networks at the same time and attach to the containers that are defined in a file called 'docker-compose.
With the typo corrected, the process moved a little faster, since Docker cached the first step rather than redownloading the base image. But as you can see from the output, we have a new error.
When the container starts, you’ll see a root prompt waiting for instructions: Now that you have a running container, let’s look at what kinds of problems you might run into. When you run a container the way you just did, without explicitly setting a name, Docker assigns a random name to the container.
This generally means that if you got to a certain step, then all of the previous steps completed successfully. Let’s create a little project to explore some issues you might encounter with a Dockerfile.
You can visit the Docker web site or follow the official installation documentation to install Docker on your local machine. The most common place you may run into issues is when you’re building your Docker image from a Dockerfile. Before we dive in, let’s clarify the difference between images and containers.
If you go to this link, then 3.4.13 doesn't exist anymore
https://www.apache.org/dist/zookeeper/
You can change to ENV ZOOKEEPER_VERSION 3.4.14, or just use an existing Zookeeper Docker image
