This README file explains how to build a simple shell script manifest ACAP application. It is achieved by using the containerized API and toolchain images.
Together with this README file, you should be able to find a directory called app. That directory contains the "shell-script-example" shell script file which can easily be run with the help of the tools and step by step below.
These instructions will guide you on how to execute the code. Below is the structure and scripts used in the example:
shell-script-example
├── app
│ ├── shell_script_example
│ ├── LICENSE
│ ├── Makefile
│ └── manifest.json
├── Dockerfile
└── README.md
- app/shell_script_example - Shell script application which writes "Hello World!" to system-log.
- app/LICENSE - Text file which lists all open source licensed source code distributed with the application.
- app/Makefile - Empty Makefile. Necessary for the build process.
- app/manifest.json - Defines the application and its configuration.
- Dockerfile - Docker file with the specified Axis toolchain and API container to build the example specified.
- README.md - Step by step instructions on how to run the example.
Below is the step by step instructions on how to execute the program. So basically starting with the generation of the .eap file to running it on a device:
Standing in your working directory run the following commands:
Note
Depending on the network you are connected to, you may need to add proxy settings. The file that needs these settings is:
~/.docker/config.json
. For reference please see https://docs.docker.com/network/proxy and a script for Axis devices in the ACAP documentation.
docker build --tag <APP_IMAGE> .
<APP_IMAGE> is the name to tag the image with, e.g., shell_script_example:1.0
Copy the result from the container image to a local directory build:
docker cp $(docker create <APP_IMAGE>):/opt/app ./build
The working dir now contains a build folder with the following files:
shell-script-example
├── app
│ ├── shell_script_example
│ ├── LICENSE
│ ├── Makefile
│ └── manifest.json
├── build
│ ├── shell_script_example*
│ ├── shell_script_example_1_0_0_armv7hf.eap
│ ├── shell_script_example_1_0_0_LICENSE.txt
│ ├── LICENSE
│ ├── Makefile
│ ├── manifest.json
│ ├── package.conf
│ ├── package.conf.orig
│ └── param.conf
├── Dockerfile
└── README.md
- build/shell_script_example* - Application shell script file.
- build/shell_script_example_1_0_0_armv7hf.eap - Application package .eap file.
- build/shell_script_example_1_0_0_LICENSE.txt - Copy of LICENSE file.
- build/manifest.json - Defines the application and its configuration.
- build/package.conf - Defines the application and its configuration.
- build/package.conf.orig - Defines the application and its configuration, original file.
- build/param.conf - File containing application parameters.
Installing your application on an Axis video device is as simple as:
Browse to the following page (replace <AXIS_DEVICE_IP> with the IP number of your Axis video device)
http://<AXIS_DEVICE_IP>/index.html#apps
Goto your device web page above > Click on the tab App in the device GUI > Add (+) sign and browse to the newly built shell_script_example_1_0_0_armv7hf.eap > Click Install > Run the application by enabling the Start switch
Application log can be found directly at:
http://<AXIS_DEVICE_IP>/axis-cgi/admin/systemlog.cgi?appname=shell_script_example
