BLUESKY_ENV -> BLUESKY_ENVIRONMENT

consistency with existing usage at APS

start soft IOCs when workstation starts

See Method 2 at https://www.2daygeek.com/execute-run-linux-scripts-command-at-reboot-startup/

# crontab -e

@reboot /home/apsu/bin/start_iocs.sh

Show interim progress during subprocess call (starting IOCs)

When instrument.iocs.check_iocs is run from blueskyStarter.sh, it can take a long time to complete. During this time, no output is shown to the console. Consider showing a progress bar or the interim output from the subprocess call. At least print a message that the step may take a minute or more to complete.

caQtDM userCalcs10.ui does not display all widgets

Expecting more content, like this MEDM display

Need to initialize the EPICS scaler channels with expected names `I0` & `diode`

Need to initialize the EPICS scaler channels with expected names I0 & diode

Originally posted by @prjemian in #15 (comment)

check that IOCs are started when instrument package is imported

example here: https://github.com/prjemian/ipython-vm7/tree/main/profile_bluesky/startup/instrument/iocs

caQtDM problem with Enable button

starting caQtDM in the new container, the pop-up menu buttons for area detector plugin Enable PVs are all white and do not respond to mouse clicks.

blueskyStarter.sh: support start_iocs

Listed as TODO item now

refactor .create for instrument package here

With #12, the instrument package is part of this repo. Revise the instructions for the new repo content. Start with a git clone https://github.com/BCDA-APS/epics-bluesky-vm ~/bluesky before the first shell script is run. Need to sudo apt install git before git clone.

caQtDM could not load any plugin

Not getting all the widgets to display properly.

OS alternatives

add example class data

As shown in https://github.com/BCDA-APS/bluesky_instrument_training/tree/main/resources/example-data -- or generate new. However, the existing set of data has good variety.

convert planning.md into shell scripts

add instrument package to this repo

Add the instrument package to this repository, so that this repo can be fully separated from bluesky_instrument_training. That repo was created for the 2021-03 training sessions.

prepare VM image

Prepare the first VM image. Needs instructions how to download, install, get started. Post in ANL's Box account.

Explain each step.

registers IOC not starting

This is checked for and started during instrument package startup. But it does not stay running.

VM image should be <10 GB

Discovered a 10GB download limit at APS, rebuild the VM to be smaller than that.

Still, allow for 40GB virtual disk size

remove unnecessary packages from OS install

After the OS is installed but before the first update, remove the largest of the packages that are not used by the training software.

Includes:

LibreOffice
Can save up to 2 GB for the image.

Do this before installing updates or the training stack since the total size of the VM image never decreases. (The host storage used by the VM expands to fit the content of the VM as installed.)

update docker images

There's a ]new release (v1.1) of the EPICS docker images](https://github.com/prjemian/epics-docker/releases/tag/1.1). Upgrade per instruction.

increase size of virtual disk

The 30GB disk is no 88% full. Increase to 40 GB (and be conservative about disk usage). The Disk Usage tools can help identify where the space is used.
