TODO List

1. Rewrite sendevent so that it accepts multiple commands at once
2. Explore the possibility to reject starting activities that outside the package scope
3. Make instrumentation more uniform and explain how to instrument apps for the framework.

Prerequisites

• Ubuntu 16.04 or later

• Access to /dev/kvm:

  chmod 777 /dev/kvm

• docker 17.03 or later

• docker-compose 1.12.0 or later

Getting Started

1. Execute git clone https://github.com/stlab-unt/Caret-HM.git
2. Modify .env:

• Set USER_ID, GROUP_ID to your user and group id
• Set EMU_NUM to a number of desired emulators (usually, number of cores - 2)
• Set TEST_DIR and SQL_DATA to the desired directories

3. Set permissions of TEST_DIR and SQL_DATA to 777:

   chmod 777 (YOUR_TEST_DIR) (YOUR_SQL_DATA)

4. If VNC password needs to be modified, change it in .env and conf/pgsql/002-create-admin-user.sql

   Alternatively, you can change VNC password only in .env and change it in the Guacamole web interface later.

5. Start dockerd, if necessary:

   sudo dockerd

6. In the folder, execute:

   docker-compose build

7. Verify that /dev/kvm is accessible, otherwise give permissions:

   chmod 777 /dev/kvm

8. Start containers:

   docker-compose up

9. Once all containers are up, you should be able to access the framework at:

   http://localhost/ - for emulator access

   http://localhost/jsac - for heatmap generation

10. If your EMU_NUM is larger than 1, you will need to add additional virtual machines to Guacamole. To do so, login as guadmin to Guacamole and add additional virtual machines. The ports start from 6001 to 6000+EMU_NUM

11. Additional configuration options available in conf and the corresponding -docker folders.

Frequently asked questions

Docker requires sudo everytime I run it, what should I do?

Make sure that your user in docker group, the detailed answer is available here.

My tests are not saved, why?

Make sure that permissions for TEST_DIR and SQL_DATA are set to 777.

Something does not work, what should I do?

• The first place to start is always to check permissions.
