How to mount storage

Installing and Using OpenWrt
1

I would like to install docker but i am running into a problem .
I have to mount my storage to /opt/ (docker) but i can't shame shame
I googled and did not found anything to point me in the right direction i did install block-mount.
And tried adding a mountpoint but i do not see the mount point in the Mounted file systems.
this is the tekst in the dockerd openwrt what i need to do.

Install Docker Community Edition

install docker-ce package for the commandline tools
install luci-app-dockerman package to get a control panel for docker containers in Luci

the default folder for docker in the dockerman luci interface is /opt/docker so you want to mount your storage at /opt or change the folder in Docker –> Overview –> Docker Root Dir and then restart the whole device, or the dockerd service.

sure these are openwrt instructions ?

Available openwrt packages in 21.02.

This is what I try to follow

They seem outdated, or the packages aren't built for some reason :confused:

Well if I install the docker packages it does not work out of the box. :smile::smile:
Hoped following this guide would make it work haha. Do you know on how to get this to work ?Or is it off Google???:smile:

you could try to downgrade to 19.07, or at least check the package availability for both releases in https://downloads.openwrt.org/

I've got the same problem. I'm playing with OpenWRT (22.03.03 x86-64) in a Hyper-V VM. Here's what it looks like before I install the docker packages:

root@openwrt64:/# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root               993.5M     42.4M    935.1M   4% /
tmpfs                     1.9G     64.0K      1.9G   0% /tmp
/dev/sda1                16.0M      5.7M     10.2M  36% /boot
/dev/sda1                16.0M      5.7M     10.2M  36% /boot
tmpfs                   512.0K         0    512.0K   0% /dev
root@openwrt64:/#

note the /dev/root line

Then I do lsblk and get this:

root@openwrt64:~# lsblk
NAME     MAJ:MIN RM    SIZE RO TYPE MOUNTPOINTS
sda        8:0    0      1G  0 disk
├─sda1     8:1    0     16M  0 part /boot
│                                   /boot
├─sda2     8:2    0 1006.8M  0 part /
└─sda128 259:0    0    239K  0 part
root@openwrt64:~#

Then I install dockerd (via LUCI -> software). Here's what it looks like afterward:

root@openwrt64:~# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root               993.5M    229.5M    748.0M  23% /
tmpfs                     1.9G      1.1M      1.9G   0% /tmp
/dev/sda1                16.0M      5.7M     10.2M  36% /boot
/dev/sda1                16.0M      5.7M     10.2M  36% /boot
tmpfs                   512.0K         0    512.0K   0% /dev
/dev/root               993.5M    229.5M    748.0M  23% /opt/docker
root@openwrt64:~#

Note the last line. Then I do another lsblk and get this (note the sda2 line):

root@openwrt64:~# lsblk
NAME     MAJ:MIN RM    SIZE RO TYPE MOUNTPOINTS
sda        8:0    0      1G  0 disk
├─sda1     8:1    0     16M  0 part /boot
│                                   /boot
├─sda2     8:2    0 1006.8M  0 part /opt/docker
│                                   /
└─sda128 259:0    0    239K  0 part
root@openwrt64:~#

Then I install docker (for the CLI) package, and do a docker pull and get the error:
