Secure the docker daemon with TLS

first, let's create some directories to work in

mkdir -p ./docker_certs/ca ./docker_certs/server ./docker_certs/client
cd ./docker_certs

Oracle Database in containers

Here are the steps to get an Oracle Database 19c up and running in an OCI container. Since there are several bash scripts involved, a linux machine is advised. (while WSL may work, untested).

I ran the following on Fedora 37 with podman installed and an alias docker=podman.

1. Clone Oracle's `docker-images` github repo

#SSH

move one up recursively

find . -type f -execdir mv -i {} .. \;

unzip each zip into separate directory named after zip archive

find . -name "*.zip" | while read filename; do unzip -o -d "${filename%.*}" "$filename"; done;

delete empty directories

find . -type d -empty -print [-delete]

CPU Frequency

Monitor CPU Frequency

watch -n 1 cat /proc/cpuinfo | grep "MHz"

List available CPU Frequency Governors

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governor

Show current CPU Frequency Governor

cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Kernel modesetting and automatic driver power management (kernel >= 4.8)[b]

While kernel modesetting (KMS) isn’t required, on recent debian, the intel driver requires KMS. You can also avoid having to use the nouveau xorg driver altogether (as in remove xserver-xorg-video-nouveau), and let Xorg talk to the nouveau kernel driver. You will want both kernel driver modules to run with modesetting:
