# Overview
This contains helper scripts to build & run cyclonedds core & example applications in docker.
Additionally you can also build a docker image with pre-built cyclonedds examples. This could be useful in quikly trying the examples (both IPC & network communication).

# Bulid docker image
There are two docker images you can build.

- Build cyclonedds core & examples (if you are using **ubuntu:cyclonedds**)
**NOTE** : *cyclonedds:latest* depends on image *ubuntu:cyclonedds*. You need to build *ubuntu:cyclonedds* first, if you want to use *cyclonedds:latest*.

Let's do that !
## Run examples inside the same container (uses IPC)
- Launch docker container, from the root of the project
`docker run --name cyclonedds -it -v $(pwd):/cyclonedds --workdir /cyclonedds cyclonedds:latest /bin/bash`
This will open terminal connected to docker @ root of the project.
- Launch docker container, from the root of the project
```
docker run --name cyclonedds -it --workdir /cyclonedds/build/bin cyclonedds:latest /bin/bash
```
This will open terminal connected to docker @ bin of the project, which contains sample applications.
It will look something like this
```
root@22ff409a33e1:/cyclonedds#
root@22ff409a33e1:/cyclonedds/build/bin#
```
- Navigate to `/build/bin` to run the example applications.
- From here you can run the example applications.
- To run another terminal , connected to same docker container, use the following command.
```
docker exec -it cyclonedds /bin/bash

## Run examples in different containers (uses docker networking)
- Follow the same steps as in the previous section , instead connecting to existing docker container create a new docker container.
e.g.
`docker run --name cyclonedds1 -it -v $(pwd):/cyclonedds --workdir /cyclonedds cyclonedds:latest /bin/bash`
`docker run --name cyclonedds1 -it --workdir /cyclonedds/build/bin cyclonedds:latest /bin/bash`
**NOTE** : You need to run this script from the root of the project.
At this point you can inspect the traffic using wireshark.
Open docker network interface (`docker0` on my system) in wireshark.
