# Container Code
|
|
|
|
This folder contains the container version of the unikernel services.
|
|
|
|
Each folder holds:
|
|
* The CPP file containing the code
|
|
* A **compile.sh** script to compile the CPP file into a runnable service
|
|
* A **Dockerfile** to create the container for this service
|
|
* A **create_container.sh** script to create to container from the Dockerfile
|
|
* A **run_service.sh** script to run the created container in detached mode
|
|
* A **start.sh** script that will compile the binary from code, build the Docker container and run it (in detached mode)
|
|
|
|
The following section briefly explains the steps taken.
|
|
|
|
## Pre Requisite
|
|
|
|
Before running the **compile.sh** or **start.sh** scripts, you must first build the **builder** container from the Dockerfile in this parent folder.
|
|
|
|
This can be done by running the **create_compiler.sh** script or running the following command from the CONTAINER directory:
|
|
|
|
```
|
|
docker build -t cetic/compiler .
|
|
```
|
|
|
|
## Compiling the binary (*compile.sh*)
|
|
|
|
*Requires the cetic/compiler container image*
|
|
|
|
This script will launch a new cetic/compiler image container, mapping the current folder to a folder inside the container, then it will staticaly compile the C++ code in the .cpp file in the directory and output a *runnableService* binary.
|
|
|
|
## Creating the container
|
|
|
|
This will create the service container using the **Dockerfile**.
|
|
|
|
It will use the lastest version of alpine base image and copy the **runnableService** executable inside the container.
|
|
|
|
## Running the container
|
|
|
|
When running the container, it will execute the command instructed in the **Dockerfile**.
|
|
|
|
The container will wait for the network to be up (sleep 1) then it will launch the service binary, passing the container's IP address to bind the service to as a paramater.
|
|
|
|
The script starts it in detached mode (i.e.: in the background)
|
|
|
|
**NB:** as of now, the IP address is not given statically, you must run `docker network inspect bridge` to view the IP address assigned to the container. |
