CRC Setup on Fedora Silverblue

https://gist.io/@ryanj/01b8592a04e40837ccd07b76716dbe73

slides: http://bit.ly/crc-silver

1. Silverblue Install

download an installer image: https://silverblue.fedoraproject.org/download
create USB (I used Fedora MediaWriter, linked on the /download page)
disable BIOS secure boot (a required step for some hardware)
boot from USB
wipe partition table (or partition with /var)
- manual partitioning guide: https://docs.fedoraproject.org/en-US/fedora-silverblue/installation/#manual-partition
after first login, run:
- rpm-ostree update
- systemctl reboot

2. Silverblue Setup

install OS-level dependency requirements:

rpm-ostree install qemu libvirt virt-manager

WARN: bug: https://bugzilla.redhat.com/show_bug.cgi?id=1919994 workaround: https://bugzilla.redhat.com/show_bug.cgi?id=1919994#c13

Create a libvirt group:

sudo su -	
groupadd --system libvirt	
grep -E '^libvirt:' /usr/lib/group >> /etc/group # workaround	
exit

Add your user to the libvirt group:

sudo usermod -a -G libvirt $(whoami)

Verify group membership:

groups $(whoami)

3. CRC Download

Download latest CRC release from: https://cloud.redhat.com/openshift/create/local

Tip: Remember to download or copy your CRC pull secret before leaving this page

4. CRC Install

cd ~/Downloads && tar xvJf ./crc-*.xz
mkdir -p ~/bin
mv ./crc-linux-1.23.1-amd64/crc ~/bin

5. CRC Setup

crc setup

6. CRC Startup

crc start -p ~/Downloads/pull_secret

if you don't include the -p flag, you'll need to interactively paste the pull secret during VM initialization

Tip: make sure to note the admin credentials in the log output!

Access the resulting web console with:

crc console

(proceed through a short series of SSL warnings... 1,2,3)

7. Follow-up Tasks

Visit the embedded OperatorHub service directory. Try installing an operator to enable professionally-maintained cloud service solutions on your cluster. After installation via Hub (by a cluster admin), operator-backed solutions will available for use by standard developers
Add additional user accounts, login as a normal (non-admin) user, then - try building and deploying a basic application

8. Cleanup

When you're done having fun:

Halt the VM with: crc stop
Remove the VM entirely (reclaim disk space): crc delete

disable wifi power management (attempted fix)

sudo vi /etc/NetworkManager/dispatcher.d/02-wlan-powersave-off
paste this:

IF=$1
STATUS=$2
ifaces=$(iwconfig 2> /dev/null | grep "802.11" | awk '{print $1})
for iface in $ifaces; do
    if [ "${IF}" = "$iface" ] && [ "${STATUS}" = "up" ]; then
        iwconfig ${iface} power off
        logger "${iface}: turning off powersave mode to prevent constant reconnections"
    fi
done

save and quit ESC:wq
sudo chmod 755 /etc/NetworkManager/dispatcher.d/02-wlan-powersave-off
systemctl restart NetworkManager.service

From https://askbot.fedoraproject.org/en/question/8168/proper-disabling-of-wifi-power-management/?answer=11771

Results: Connection still drops every 5 mins or so. Does not resolve on it's own. Need to click on a popup to restore the connection :(

Add media codecs (first attempt)

Recommended codec setup:

# no effect
rpm-ostree install gstreamer1-plugin-openh264 mozilla-openh264

Add RPMfusion repo (optional?)

sudo rpm-ostree install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

This works:

rpm-ostree install ffmpeg-libs compat-ffmpeg28 gstreamer1-libav gstreamer1-plugins-ugly
