Version: 2.0.0

Install with Docker

Installation Requirements

We assume Docker is installed on your system. If not, install it first: Developers - Docker .

Download and run with Docker

The following terminal command will download and run the layline.io docker container:

docker run -p 5841:5841 -p 5842:5842 docker.io/layline/layline-samples:1.2.4

Parameters:

Mapping internal Config Server port to external: 5841 --> 5841
Mapping internal Reactive Engine port to external: 5842 --> 5842
Path to layline.io docker container:
```
docker.io/layline/layline-samples:1.2.4
```

Should the external ports already be in use on your installation target, then change them to an open port to your end.

That's it! You're all set.

Configuration Center Web UI

Open Configuration Center

It's time to check if we can start the web-based Configuration Center.

Please note:

The web-based Configuration Center is served by the Configuration Server. Because the Docker image starts everything automatically, the Configuration Server should already be running.

:::: tabs ::: tab Linux/MacOS Open a web browser and enter the url: http://localhost:5841.

In case you have installed the Configuration Server on another machine reachable through a different url, then enter the respective url instead of localhost. Should you have changed the port number during installation, you also need to change the port number to what you have set it to. ::: ::: tab Windows On Windows you first need to determine the IP-Address of Docker container running layline.io. Please refer to the Docker documentation for more information.

Open a web browser and enter the url: http:// <ip-address>:5841.

If in doubt, try: http://192.168.99.100:5841 ::: ::::

You should be taken to the login page:

The default login is admin with password admin. Once logged in, you should see this:

Operations Center

Let's check the status of the Reactive Engine which auto-runs as part of the Docker image. We can do so in the Operations section of the UI (1):

Depending on whether your host system is MacOS/Linux or Windows, pick the respectively named Cluster from the drop-down menu (2).

You are currently logged in to the Configuration Server only. To monitor the Reactive Cluster you also need to separately log in to it (3). The credentials for the Cluster are user "admin" and password "admin".

Running on Windows and unable to log in?

If the IP-address of your docker image does on Windows does not default to 192.168.100.199, you are uneble to log in to the Reactive Cluster. In this case you need to change the pre-configured IP-address to the actual IP-address of you docker image. Follow these simple steps:

Head to Settings (1)
Select the Docker-Cluster-Windows in the left pane (2)
Change the IP-address to the one of your Docker container instance (3). Make sure that you leave the port as 5842. If you remove it, it's not going to work.

::: caution Important The settings will not persist if you shut down the docker container. You have the repeat change of the IP-address in that case.

Check that the Reactive Cluster is up and running:

Make sure you are logged in to the Reactive Cluster (1).
Head to Operations --> Cluster (2).
All items on the left pane should be green (3).
Select the one node in the Cluster at the bottom of the left pane. This sample Cluster runsn with only one Reactive Engine node.
On the right pane check the node status (4). It should show "Up".

If the above is true, your docker container is in good shape.

Sample Projects

The Docker container of layline.io comes with pre-installed sample Projects.

Click on Project --> Open:

Select any of the Projects (list is probably longer by the time you download layline.io) and open it.

Explore the container

Let us show you a few things inside the container.
