Changing the Size of a cSRX Container Firewall Container

Based on your specific cSRX Container Firewall deployment requirements, scale requirements, and resource availability, you can scale the performance and capacity of a cSRX Container Firewall instance by specifying a specific size (small, middle, or large). Each cSRX Container Firewall size has certain characteristics and can be applicable to certain deployments. By default, the cSRX Container Firewall container launches using the large size configuration.

Table 1 compares the scale requirements of a cSRX Container Firewall instance depending on the specified size.

Table 1: cSRX Container Firewall Size Comparison
Specification	cSRX Container Firewall: Small Size	cSRX Container Firewall: Middle Size	cSRX Container Firewall: Large Size (Default)
Physical Memory Overhead	256M	1G	4G
Number of Flow Sessions	8K	64K	512K

To assign a specific size for a cSRX Container Firewall instance, include the CSRX_SIZE environment variable in the docker run command.

For example, to launch a cSRX Container Firewall instance using the middle size configuration to scale performance and capacity:

root@csrx-ubuntu3:~/csrx# docker run -d --privileged --network=mgt_bridge -e CSRX_SIZE="middle" --name=<csrx-container-name> <csrx-image-name>
