Beamline BL22I Non Crystalline Diffraction

This repository contains a specification of the IOC instances running on the I22 beamline at Diamond Light Source.

Setting up your environment to use BL22I

Inside DLS you can access this beamline by setting up your environment as follows:

For convenience you will need ~/.local/bin in your path. To do this edit the file ~/.bash_profile and add the following line at the end:
```
export PATH="$PATH:~/.local/bin"
```
Download and apply the project's environment file using the commands below.
```
cd /tmp
curl -o ~/.local/bin/bl22i https://raw.githubusercontent.com/epics-containers/bl22i/main/environment.sh?token=$(date +%s)
. ~/.bash_profile # adds ~/.local/bin to path
. bl22i
```
You will be asked for your cluster credentials which are the same as your linux login. Note that if you have not used this cluster before you may need to ask the cloud team for access. To do so use this form and ask for access to namespace i22-iocs on cluster k8s-i22.

After logging out and back in again to pick up your profile changes you can then reload the bl22i environment with the following command:
```
. bl22i
```

Now if everything is working you should be able to see the IOC instances running on the kubernetes cluster as follows:

$ ec ps
IOC_NAME          VERSION     STATE     RESTARTS   STARTED
bl22i-ea-ioc-03   2023.10.2   Running   0          2023-10-21T19:10:33Z

You can also take a look at what other commands are available:
```
ec --help
ec ioc --help
ec dev --help
```
For a visual interface to the ioc namespace on the cluster you can use the kubernetes dashboard at this URL:
