StateChecker can be installed directly on the APIC as an ACI app or deployed in standalone mode.

Currently, the APIC imposes a 2G memory limit and a 10G disk quota on stateful applications. If an operator needs to create and maintain a large number of snapshots or to manage multiple fabrics within a single instance of the application, it may be beneficial to run the application in standalone mode.

App Mode

app mode is when the application is deployed and run on the APIC. The most recent public release can be downloaded from ACI AppCenter. After downloading the app, follow the directions for uploading and installing the app on the APIC:

Users can also build the app from source prior to installing on the APIC. See the Building ACI Application to build the app as an ACI application from source.

Standalone Mode

standalone mode allows the application to run on a dedicated host, VM, or container controlled by the operator and make remote connections to the APIC to collect the required data. There are a few options for deploying the app in standalone mode below. Once deployed, the default credentials for logging into the application are:

  • username: admin
  • password: cisco

Pre-build OVA


Details to come


The app has been developed to be deployed as an all-in-one container. This relaxes the requirements on the host machine as all dependencies are already installed within the container. To deploy the app in standalone mode, install docker and execute the following command:

docker run --name statechecker -p 5000:443 -d agccie/statechecker:latest

The container will be pulled from Dockerhub and started with an HTTPS web server running on port 5000. The application can be access via https://localhost:5000.

Deployment (Development)

The application can also be deployed in standalone mode by manually building the container and mounting the source code into the appropriate directories. Similar to the all-in-one approach, all dependencies are still installed within the container so the host machine only requires the following:

  • git
  • docker
  • linux or macOS


Deployment scripts are written in bash and have not been tested on Windows. Want to get the build script working in windows? Feel free to submit a pull request!

To begin, use git to clone the source repository:

$ git clone

Next execute the script with the -s flag to deploy the application in standalone mode. By default the build script will deploy the application running on http port (p) 5000 and https port (P) 5001. You can customize these ports using the -p and -P flags, respectively.

$ ./statechecker/build/ -h

You can validate that the container is running on the configured ports via:

$ docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                                         NAMES

Once deployed you can access the application on the host and port number you configured. If running on a local machine with default options, you would access the site at http://localhost:5000.


the build script will mount the source code as a read only directory within the container. Any development should be done on the host, not the container. Similarly, if the source code is removed from the host it will cause the application running in the container to fail.

Building ACI Application

If you are unable to download the app from the appstore or need to build from source to resolve a bug or enhancement, you can build the application from source. On the development environment, you’ll need to have the following installed:

  • git
  • docker
  • zip
  • python2.7 + pip
  • Node.js v9.8.0
  • Npm v5.8.0

First, clone the source code repo. From within the source directory, use pip to install the packager dependencies. Finally, execute the script.


If using a node or npm version higher than that listed in the requirements, used the -r flag during the build process.

$ git clone
$ cd ./statechecker
$ pip install build/app_package/cisco_aci_app_tools-1.1_min.tar.gz
$ ./build/
