pi-ci's Issues

Really slow performances

Hello there, thanks for this project.

I'm trying it in my desktop with Debian 9 but in pi-ci I'm having really really slow i/o and network performances that make it almost unusable.

I/O in my desktop:

time dd if=/dev/zero of=test.dat bs=1024 count=100000
100000+0 record dentro
100000+0 record fuori
102400000 bytes (102 MB, 98 MiB) copied, 0,314238 s, 326 MB/s

real	0m0,356s
user	0m0,048s
sys	0m0,256s

I/O in pi-ci:

100000+0 records in
100000+0 records out
102400000 bytes (102 MB, 98 MiB) copied, 62.5928 s, 1.6 MB/s

real	1m2.874s
user	0m8.865s
sys	0m49.498s

Network speed in my desktop:

Download: 19.81 Mbit/s
Upload: 18.49 Mbit/s

Network speed in pi-ci:

Download: 1.04 Mbit/s
Upload: 1.00 Mbit/s

I also tested pi-ci in a vm with debian 10 in my proxmox server with almost same results.
Are these the expected performances or I'm having problems?

How To Configure A Different OS?

Please can you describe how to configure a different OS (eg; https://en.opensuse.org/HCL:Raspberry_Pi4). Do I need to checkout and modify the source then build my own docker image, or is it possible to do this using the default image?

Also, where is this specified in the source? I think it's set via environment variables, but I can't find where the environment variables are set.

Thanks!

Cannot run with --device=/dev/mmcblk0

When use https://github.com/ptrsr/pi-ci/blob/master/tools/run.sh file, the command failed with these error:

docker: Error response from daemon: error gathering device information while adding custom device "/dev/mmcblk0": no such file or directory.

Device exists in docker container

pi@raspberrypi:~ $ ls /dev/mmc* -l
brw-rw---- 1 root disk 179, 0 Sep 28 13:36 /dev/mmcblk0
brw-rw---- 1 root disk 179, 1 Sep 28 13:36 /dev/mmcblk0p1
brw-rw---- 1 root disk 179, 2 Sep 28 13:36 /dev/mmcblk0p2

this command works:

docker run --rm -it -v $(realpath .)/dist:/dist ptrsr/pi-ci start

Continuous errors

It is a brilliant solution running in docker. I continuously get error on docker screen about inode checksum error:

[  time] EXT4-fs error (device mmcblk0p2): ext4_lookup:1701: inode #45072: comm <anycommand>: iget: checksum invalid

It is a very new, clean install of dockerfile.
