Using ECS as an NFS Server to Isolate Resources of Multiple Users describes using an ECS as the NFS server to isolate resources when multiple users use the Stable-Diffusion WebUI. This solution is applicable to scenarios where strong isolation is required between users.

In some scenarios, if you want multiple users to share some resources, such as model files and plug-ins, the storage space is wasted if each user copies a file. This problem can be solved by mounting different applications to the same SFS file system. However, user operations and configurations may interfere with each other, perform the following operations to solve it:

The following operations take user1 and user2 in Using ECS as an NFS Server to Isolate Resources of Multiple Users as an example. You need to create a Stable-Diffusion application for each of the two users and use the same SFS file system to initialize the custom model. For details, see Application Creation and Deployment and Custom Models. In this case, the two users have shared the model and plug-in. The subsequent steps will solve the operation and configuration isolation problem.

Creating a Configuration File

Open the file management page of any user by referring to step 4 in Initializing a Model. After login, go to the sd directory. If the sd directory does not exist or the config.json file does not exist in the directory, start the WebUI of any user by referring to Application Use and perform operations in this document again.

Locate the config.json file, copy it to the sd directory, and rename it to config_user1.json. Repeat for user2, naming the copied file to config_user2.json.

Modifying Environment Variables and Using the New Configuration File

In Creating a Configuration File, you have created a configuration file for each user. Now, modify environment variables to enable different users to use their own configuration files. Configure the following environment variables for the Stable-Diffusion function by referring to Environment Variables and save the settings (you can set the environment variables together with API Access and Enabling WebUI Authentication). The following are the environment variables of user1 and user2.

**Table 1** Environment variables of user1 and user2
Key	Value
EXTRA_ARGS	--ui-settings-file=/mnt/auto/sd/config_user1.json
EXTRA_ARGS	--ui-settings-file=/mnt/auto/sd/config_user2.json

Changing the Path for Saving Images

After the preceding configurations are complete, the two users can share models and plug-ins without affecting each other. To further isolate the inference results of different users, you can change the result save path in the settings.
