Re^5: approximating geological problems with highway data

Host your own instance and avoid such problems, or at least be in a position to fix them yourself.

I've been working on the docker part, taking my lumps but not bringing it up, as it isn't perl proper. I had a setback with following outdated instructions on the first attempt. I found a nice fresh how-to-install-docker-on-linux, from 31 January 2023, and have made considerable progress, but I can't quite get to where I successfully pull files. Fuller story in readmores:

All these commands went off without complaint:

apt update
apt-get remove docker docker-engine docker.io containerd runc

apt-get update
apt-get -y install ca-certificates curl gnupg lsb-release
mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --d
+earmor -o /etc/apt/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrin
+gs/docker.gpg] https://download.docker.com/linux/debian $(lsb_release
+ -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/n
+ull


apt-get update
apt-get install -y docker-ce docker-ce-cli containerd.io docker-compos
+e-plugin

systemctl start docker
systemctl enable docker
[download]

Output for root:

root@mypi:~# docker info
Client:
...

Server:
 Containers: 0
...
WARNING: No blkio throttle.write_iops_device support
root@mypi:~#

Looks all good. But then as pi, I failed:

root@mypi:~# exit
logout
$ which docker
/usr/bin/docker
$ docker info
Client:
...

Server:

Then I thought, gosh, root can give pi permissions like this:

usermod -aG docker pi
[download]

, restart and see if I can pull some files:

$ docker info
...

I didn't understand this ultimate command, and I don't find any evidence of

/code
[download]

on my machine.

Q1) Do I need to be worried about this mismatch?

I know I've downloaded 1.2 gigs of data, but I don't know where: (?)

$ df -h

/dev/root        29G  9.8G   18G  36% /
