How to configure a proxy for IBM Resilient Circuits

If you want to exclude certain hosts (for example the URL in your internal network) from the proxy, you need to use the "no_proxy" environment variable.

For example, to exclude the proxy when connecting to resilient.example.com, you use

export no_proxy=resilient.example.com,resilient.localdomain,127.0.0.1

If IBM Resilient Circuits is started as a systemd service you can add the proxy settings to the services file.

1. Open and edit the file "/etc/systemd/system/resilient-circuits.service".

2. Find the section "[Service]", add the following lines:

Environment=HTTP_PROXY=http://proxy:8080
Environment=HTTPS_PROXY=https://proxy:8080
Environment=NO_PROXY=resilient.example.com,resilient.localdomain,127.0.0.1

3. Save the changes.

4. Load the changes and restart the service by command:

sudo systemctl daemon-reload
sudo systemctl restart resilient-circuits

The NO_PROXY environment variable specifies URLs that should be excluded from proxying (on servers that should be contacted directly). This should be a comma-separated list of hostnames, domain names, or a mixture of both.

If you need to exclude all URLs which match a subdomain, do not use "*.suddomain.com" in "NO_PROXY". You should use "subdomain.com" or ".subdomain.com" instead.

For IBM Resilient Circuits running on Windows

You need to set the same environment variables on Windows following the steps below:

1. Go to Control Panel > System > Edit the system environment variables.

2. In the "System Properties" window, select "Advanced" tab, click button "Environment Variables".

3. Click "New ..." to add environment variables of HTTP_PROXY, HTTPS_PROXY and NO_PROXY. Click "OK" and "Apply".

4. Restart IBM Resilient Circuits from the command line or from the Windows service.
