The available software versions for Zixi Broadcaster (which are available for your account) are displayed towards the top of the page. The “linux64” build is an X86\_64 build that should run on any Intel or AMD X86\_64 CPU system. ::: :::WorkflowBlockItem Click on the box of the version that you would like to install. The download options for the selected version are displayed. ::Image[]{src="https://api.archbee.com/api/optimize/mzxtTQEvCNIdUNgF2kuwJ/wfQ7tOtgXcgViAIg-JOWz_image.png" size="70" width="1311" height="629" position="center" darkWidth="1311" darkHeight="629" showCaption="false"} ::: :::WorkflowBlockItem To download the Docker image file, click on the **Download** button next to the Docker file and navigate to the location where you would like to save the file. Alternatively, you can download the Docker image file by clicking on the **>\_CLI** button next to the Docker image file and executing the `wget` command that is provided. ::: :::WorkflowBlockItem Extract the installation file by typing the following command: ```bash gzip -d -.docker.tar.gz ``` where `` is “zixi\_broadcaster” and `` is similar to “16.4.44543”. ::: :::WorkflowBlockItem Import the .tar Docker file image into your local Docker environment using the load command as shown below: ```bash docker load --input -.docker.tar ``` At this point the Docker image is defined in your the local environment, but the Docker container is not yet running ::: :::: ### To build a new Docker image: ::::WorkflowBlock :::WorkflowBlockItem Copy the contents of [Appendix A](docId:39cP1cpAafwr1k68k9eUB) and [Appendix B](docId\:KsEY4ljPoa-Z-p30yC92N) into files named “dockerfile\_zixi\_broadcaster.txt” and “broadcaster-config-template.xml”, respectively. ::: :::WorkflowBlockItem Place the files into the current working directory. ::: :::WorkflowBlockItem If you don’t already have the required installation file, you can obtain following the steps in [the section above](docId\:uBFM4G3PsqVgURGW6ULDU). ::: :::WorkflowBlockItem Copy the Broadcaster .tar.gz installer file into the working directory. ::: :::WorkflowBlockItem Edit the dockerfile\_zixi\_broadcaster.txt file with the correct version number for the Broadcaster installer. ::Image[]{src="https://api.archbee.com/api/optimize/mzxtTQEvCNIdUNgF2kuwJ/0p4Xiln4-hOO7eLwK7SQE_image.png" size="64" width="645" height="175" position="center" darkWidth="645" darkHeight="175" showCaption="false"} ::: :::WorkflowBlockItem Run the following Docker build command, which will execute steps in the specified Docker file. ```bash docker build --no-cache --tag - --file ./dockerfile_zixi_broadcaster.txt . ``` The dockerfile\_zixi\_broadcaster.txt file contains embedded comments describing how the image is being built. After the image is built, you will have an image in your local Docker environment. ::: :::WorkflowBlockItem Use the following command to see available images: ```bash docker images ``` The output will be similar to the following (with different image IDs): ```bash REPOSITORY TAG IMAGE ID CREATED SIZE zixi broadcaster 16.4.44543 855f142a53a7 24 minutes ago 549MB centos 7 B5b4d78bc90c 5 weeks ago 203MB ``` ::: :::WorkflowBlockItem After building the Docker image, you can save the image to a file that can be easily shared to someone else. To save the image to a file, use the save command as shown below: ```bash docker save zixi_broadcaster: > zixi_broadcaster-.docker.tar ``` ::: :::WorkflowBlockItem You can use the repository and tag to specify the image, as shown above, or you can use the image ID. ::: :::WorkflowBlockItem After saving the image, you can “gzip” it to save space ::: ::::
