Docker firmware selector rootfs size

[fabri1]

Hello,

I have a question about the firmware selector, I need to create a build for x86 with docker packages (docker docker-compose dockerd luci-app-dockerman luci-lib-docker)

Unfortunately when I go to create the build it reports the error out of space...

Is there a way to generate the build larger than allowed? Unfortunately the docker packages are large...

Ignoring, exclude it (-e/-ef) to override.
error: ext4_allocate_best_fit_partial: failed to allocate 4565 blocks, out of space?
make[3]: *** [/builder/include/image.mk:399: /builder/build_dir/target-i386_pentium4_musl/linux-x86_generic/root.ext4] Error 1

Overriding CONFIG_TARGET_ROOTFS_PARTSIZE in Image Builder

I'm trying to build a custom x86 image with Image Builder with non-default rootfs size. I can manually (or with sed) edit the .config file and change CONFIG_TARGET_ROOTFS_PARTSIZE value, but is there a way to do it from the command line? So far I've tried the following none, of which worked for me: make CONFIG_TARGET_ROOTFS_PARTSIZE=512 image export CONFIG_TARGET_ROOTFS_PARTSIZE=512 make -e image export MAKEFLAGS="CONFIG_TARGET_ROOTFS_PARTSIZE=512" make image export CONFIG_TARGET_ROOTF…

You can mount separate partition on the 2nd half of the disk.
squashfs is more reliable and "router-like" as you can fsck overlay and revert to factory files if you need.

thanks for the great replay!

I thought maintenance was more... "fast".
It would be nice to have a subscription for "stable updates" without having to manually create a build every time.

For 24.10 and later, Firmware Selector is the only ASU client that does not support resizing the rootfs partition. If you can use on-device clients for your upgrades (LuCI Attended Sysupgrade or owut), then they can be used to perform the ASU builds and include a non-default value for the rootfs partition size (up to 1024MB when using the OpenWrt ASU server).

LuCI Attended Sysupgrade

Thanks a lot! I will try with LuCI Attended Sysupgrade and understand how to maintain the current disk size... do you already have some reference?

@fabri1

do you already have some reference?

Assuming your version of LuCI Attended Sysupgrade is new enough, then use https://openwrt.org/docs/guide-user/installation/sysupgrade.owut#expanding_root_file_system LuCI now looks for the owut setting and uses that.
