Introduction
In this article, we will discuss the Upgradation Concept in Puppet Remediate. Puppet Remediate is used to check the vulnerabilities in the software. It helps you minimize the faults and external errors in your computer by providing visibility of these errors before they occur. We will look at how we can upgrade puppet remediate in different ways. We will look at the upgradation of the puppet in online, offline, and custom registry modes.
We will discuss all this through commands and steps. Upgrading puppets can be done in both ways. The online and the offline ways. An explanation of both is given below.
Upgradation in Online Mode👨💻
In this, we will discuss the upgradation concept in puppet remediate in the online mode.
Upgrade puppet Remediate on a node with a new version can be done in a few simple commands with internet access.
The commands are mentioned below:
Update puppet Remediate to the latest version.
Run the Remediate update command.
docker-compose run remediate update
If your TLS is configured for the Docker daemon, the above update command fails to perform.
Before running the update command, it is crucial to stop the Remediate and remove theoauth_client.json file if upgrading from Remediate 1.1.x.
Remove the JSON file by using the below command.
First, stop the Remediate.
docker-compose run remediate stop
Remove the JSON file.
docker secret rm oauth_client.json
When upgrading from Remediate 1.2.x or later, you don’t have to perform the above commands.
Upgradation in Offline Mode👨💻
In this, we will discuss the upgradation concept in puppet remediate in the offline mode.
Upgrade puppet Remediate on a node with a new version can be done in a few simple commands on offline machines.
When upgrading puppet remediates on offline mode, follow the below command:
1️⃣When the node has an internet connection you must download the following files.
You don't need to do the steps above when using a custom Docker registry.
2️⃣ Verifying image bundle and offline docker-compose.yml files signatures can also be done.
Using an asymmetric key private key portion, a digital signature gets created whenever a new puppet Remediate is released. You can validate the signature using the same asymmetric public key portion.
When everything is perfect, and your signature gets valid, the response you will get is mentioned below:
Verified Ok
3️⃣Wherever you want to install the remediate, you will copy the bundle and the offline docker file you have installed to the offline node where you want to install remediate.
4️⃣You will be required to run the Docker load command. The command is mentioned below:
docker load -i images.tar.gz
5️⃣In the next step, you will stop the remediate.
docker-compose run remediate stop
6️⃣To run the remediate with your license and replace the other, run the following command
docker-compose run remediate start -o --license-file ./your-license.json
Upgrade From a Custom Registry👨💻
In this, we will discuss the upgradation concept in puppet remediate using the custom registry. You can also upgrade the remediate when you use a custom registry with a few simple commands.
Prerequisites
Before you use a custom registry to upgrade the remediate, carry out the following tasks:
🟢Ensure that you have received your license and that your system meets the requirements of the new version of the remediate.
🟢To the place where you want to install the remediate images, make sure that your license is added to the node.
🟢You should set the Registry environment to point to the URL of the custom docker registry whenever you use a custom registry to store the remediate docker images. Ex:
In the above example, for downloading the images it needs, Remediate to contact my-custom-docker-registry.local.net.
1️⃣In the same directory as your license, download the remediateDocker File.
2️⃣The next step is to stop the remediate. The command is mentioned below:
docker-compose run remediate stop
3️⃣To run the remediate with your license and replace the other, run the following command. Run the remediate start command
docker-compose run remediate start --license-file your-license.json
