Upgrading the cloud node image¶
These instructions describe the steps to upgrade the cloud node image 4.x deployed on AWS or GCP up to 5.0.
To upgrade the end‑of‑life node (3.6 or lower), please use the different instructions.
Requirements¶
-
Access to the account with the Administrator role in Wallarm Console in the US Cloud or EU Cloud
-
Access to
https://us1.api.wallarm.com
if working with US Wallarm Cloud or tohttps://api.wallarm.com
if working with EU Wallarm Cloud. Please ensure the access is not blocked by a firewall -
Access to the IP addresses below for downloading updates to attack detection rules and API specifications, as well as retrieving precise IPs for your allowlisted, denylisted, or graylisted countries, regions, or data centers
Step 1: Launch a new instance with the filtering node 5.0¶
-
Open the Wallarm filtering node image on the cloud platform marketplace and proceed to the image launch:
-
At the launch step, set the following settings:
- Select the image version
5.0.x
- For AWS, select the created security group in the field Security Group Settings
- For AWS, select the name of the created key pair in the field Key Pair Settings
- Select the image version
-
Confirm the instance launch.
-
For GCP, configure the instance following these instructions.
Step 2: Connect the filtering node to Wallarm Cloud¶
-
Connect to the filtering node instance via SSH. More detailed instructions for connecting to the instances are available in the cloud platform documentation:
-
Create a new Wallarm node and connect it to the Wallarm Cloud using the generated token as described in the instructions for the cloud platform:
Step 3: Copy the filtering node settings from the previous version to the new version¶
Copy the settings for processing and proxying requests from the following configuration files of the previous Wallarm node version to the files of the filtering node 5.0:
-
/etc/nginx/nginx.conf
and other files with NGINX settings -
/etc/nginx/conf.d/wallarm-status.conf
with the filtering node monitoring service settings -
/etc/environment
with environment variables -
any other custom configuration files for request processing and proxying
Detailed information about working with NGINX configuration files is available in the official NGINX documentation.
The list of filtering node directives is available here.
Step 4: Restart NGINX¶
Restart NGINX to apply the settings:
Step 5: Test Wallarm node operation¶
-
Send the request with test Path Traversal attack to a protected resource address:
-
Open Wallarm Console → Attacks section in the US Cloud or EU Cloud and make sure the attack is displayed in the list.
Step 6: Create the virtual machine image based on the filtering node 5.0 in AWS or GCP¶
To create the virtual machine image based on the filtering node 5.0, please follow the instructions for AWS or GCP.
Step 7: Delete the previous Wallarm node instance¶
If the new version of the filtering node is successfully configured and tested, remove the instance and virtual machine image with the previous version of the filtering node using the AWS or GCP management console.
