The following article explains how to install, uninstall, and regenerate BlazeMeter's on premise agent on your server/instance behind your firewall.

First, make sure your server/instance meets the minimum requirements as described in this article.

• Installation Process
• Uninstall/Remove Ship
• Regenerating Ship

Installation Process:

1. Navigate to the Harbor where you want to create the ship: going to your Account Settings -> Workspaces -> Private Locations and choose the harbor.
   
2. Choose "Add agent".
   
3. Provide a name for the new Agent, and optionally, the IP address of the machine.
   
   
4. An installation script will be generated - Copy the script and run it on your private engine
   NOTE: Installing the agent inside the Docker requires sufficient permissions. 
   NOTE: When installing an agent behind a corporate proxy, follow these additional steps
   NOTE: When installing an agent that uses a CA certificate, follow these additional steps
   
5. Once the script has finished running, a 4GB file will be downloaded in the background.
   Downloads can take up to 30 minutes - during this time, the new agent will be listed in the Harbor, but will not have a heartbeat.
   Once the download has finished,  the ship will show a live heartbeat and will be available for use.
   
   
6. Optional: You can check the downloaded docker images using the following command:
   

   $ sudo docker ps -a

   You should see the something similar to the following if you have all the needed images:
   

   REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
   
   taurus-cloud                61                  b96d0e5b4821        11 days ago         3.76GB
   
   taurus-cloud                latest              b96d0e5b4821        11 days ago         3.76GB

How to Uninstall/Remove Ship:

1. Log in to the machine containing the agent you want to uninstall/remove, and run the following command to list all the containers:
   

   $ sudo docker ps -a

   You will see a response similar to the one below:
   

   CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
   
   54c0b773a855 blazemeter/crane "bash" 2 days ago Up 2 days 2 days ago blazemeter-crane

   You should see the status as running.
   
   
2. If you are seeing an 'Idle' status in BlazeMeter, you will need to use the following command to stop the container:
   

   $ sudo docker stop <Container_ID>

   You need the container ID from the previous step to run this command, which will change the container to an 'Exited' status.
   
   
3. Remove the <blazemeter/crane> container using the following command:
   

   $ sudo docker rm <Container_ID>

4. To remove all the images for the OPL, list out all the images on the machine using the following command:
   

   $ sudo docker images

   You will see something like the following:
   

   REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
   
   taurus-cloud                61                  b96d0e5b4821        11 days ago         3.76GB
   
   taurus-cloud                latest              b96d0e5b4821        11 days ago         3.76GB
   
   apm-image                   1.0.42              675382697ac6        2 weeks ago         281MB
   
   apm-image                   latest              675382697ac6        2 weeks ago         281MB
   
   blazemeter/crane            1.0.98              63d6406c5dab        5 weeks ago         700MB
   
   blazemeter/crane            latest              63d6406c5dab        5 weeks ago         700MB
   
   blazemeter                  1.0.16              f0cbfb17c75b        5 weeks ago         5.46GB
   
   blazemeter                  latest              f0cbfb17c75b        5 weeks ago         5.46GB
   
   blazemeter/proxy-recorder   1.3.3-345           2b188b359b0a        3 weeks ago         1.13GB
   
   blazemeter/proxy-recorder   latest              2b188b359b0a        3 weeks ago         1.13GB
   

5. To remove all the images, use the following command:
   

   $ sudo docker rmi $(docker images -a -q)

   OR
   
   If there is an issue with removing one or more of the images, you can use the following command to force delete it:
   

   $ sudo docker rmi --force $(docker images -a -q)

   OR
   
   If you have other images on your Docker instance and you want to only remove the images used for BlazeMeter, you can use the following command:
   

   $ sudo docker rmi <Image ID of apm-image> <Image ID of blazemeter/proxy-recorder> <Image ID of taurus-cloud> <Image ID of blazemeter-quicktest> <Image ID of blazemeter> <Image ID of blazemeter/crane>

6. Finally, go to the Private Location containing this agent and click the 'Delete' button, as shown in the screenshot below:
   
   
   
   You will be prompted if you would like to complete this action, which you can complete by clicking 'OK'.
   
   

Regenerating a Ship:

Sometimes, you will need to regenerate a ship if something goes wrong with the initial install. The following steps describe what you will need to do:

1. Navigate to the Private Location of the agent in question and click the 'Regenerate' button, as shown below:
   
   
   
   You will receive a prompt to continue, which you can complete by clicking 'OK'. You will then see another docker run command come up, similar to the one below:
   
   Copy this command and save in a safe place for later. If you are using a proxy, you will need to add the necessary information, as discussed in this article.
2. Log on to the agent machine, and run the following command:
   

   $ sudo docker ps -a

   If you see a response that lists a <blazemeter/crane> container, then continue to next step. If you do not see a <blazemeter/crane> container, skip to Step 4.
3. Remove the container with the following commands (the Container_ID is found from the previous steps command):
   

   $ sudo docker stop <Container_ID>
   $ sudo docker rm <Container_ID>

4. Optional: If you are having issues with the images for your installation, you will need to run the following command to remove the images:
   
   Removes all Docker images
   

   $ sudo docker rmi $(docker images -a -q)

   OR
   
   Force removes all Docker images (in case of failure to delete)
   

   $ sudo docker rmi -f $(docker images -a -q) (In case the images fail to delete)

   OR
   
   Remove all BlazeMeter related images (in case of non-BlazeMeter images in Docker instance)
   

   $ sudo docker rmi <Image ID of apm-image> <Image ID of blazemeter/proxy-recorder> <Image ID of taurus-cloud> <Image ID of blazemeter-quicktest> <Image ID of blazemeter> <Image ID of blazemeter/crane>

5. Run the docker run command that was generated in Step 1, and wait a few moments for the test to give an idle status, as shown below:
