How to install k3s into yocto image on IMX8MP(hardknott)

[Yuki_S]

I want to include k3s in my Yocto image.

I edited local.conf as below, but a build error occurred.
That log is attached.

MACHINE ??= 'imx8mp-lpddr4-evk'
DISTRO ?= 'fsl-imx-xwayland'
PACKAGE_CLASSES ?= 'package_rpm'
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS ??= "\
STOPTASKS,${TMPDIR},1G,100K \
STOPTASKS,${DL_DIR},1G,100K \
STOPTASKS,${SSTATE_DIR},1G,100K \
STOPTASKS,/tmp,100M,100K \
ABORT,${TMPDIR},100M,1K \
ABORT,${DL_DIR},100M,1K \
ABORT,${SSTATE_DIR},100M,1K \
ABORT,/tmp,10M,1K"
PACKAGECONFIG_append_pn-qemu-system-native = " sdl"
CONF_VERSION = "1"

DL_DIR ?= "${BSPDIR}/downloads/"
ACCEPT_FSL_EULA = "1"

# Switch to Debian packaging and include package-management in the image
PACKAGE_CLASSES = "package_deb"
EXTRA_IMAGE_FEATURES += "package-management"

IMAGE_INSTALL_append = " k3s"

Please let me know this solution.

Best regards.

Hi @Yuki_S 

Please follow the build log, append the 'seccomp'  into DISTRO_FEATURES

Hi, @Zhiming_Liu ,

Thank you for your reply.

I edited local.conf as below.

MACHINE ??= 'imx8mp-lpddr4-evk'
DISTRO ?= 'fsl-imx-xwayland'
PACKAGE_CLASSES ?= 'package_rpm'
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"

PATCHRESOLVE = "noop"
BB_DISKMON_DIRS ??= "\

PACKAGECONFIG_append_pn-qemu-system-native = " sdl"
CONF_VERSION = "1"

DL_DIR ?= "${BSPDIR}/downloads/"
ACCEPT_FSL_EULA = "1"

# Switch to Debian packaging and include package-management in the image
PACKAGE_CLASSES = "package_deb"
EXTRA_IMAGE_FEATURES += "package-management"

DISTRO_FEATURES:append = " seccomp"
IMAGE_INSTALL_append = " k3s"

But a following build error occurred.

Am I doing something wrong…?

Or is there another solution?

You can use L5.15.32+ which can support k3s in my side.

[Yuki_S]

Thank you for your reply!!

I tried with L5.15.32+ on other PC and k3s build was successful as you say.

However, my PC is built in the LF5.10.72_2.2.0 environment, and I cannot build in this environment.

Is k3s not supported in the LF5.10.72_2.2.0 environment?

（By the way, LF5.10.72_2.2.0 seems to have a recipe for k3s.）

cd ~/work/imx-yocto-bsp
source setup-environment build-xwayland
bitbake-layers show-recipes

=== Available recipes: ===
a2jmidid:
meta-oe 9
kubernetes:
meta-virtualization v1.20.9+git7a576bc3935a6b555e33346fd73ad77c925e9e4a

It seems that this version miss some patchs about gnutls and seccomp in this release:

https://gerrit.openbmc.org/plugins/gitiles/openbmc/openbmc/+/refs/heads/hardknott%5E%21/

Armin Kuster's patch:

Khem Raj's patch

gnutls: Point to staging area for finding seccomp libs and includes

 I don't recommand you use hardkott.

[Yuki_S]

Thank you for your reply!!

I didn't realize the patch was missing...

There is also a method that can be executed with a binary on the Rancher site, so we will consider that method as well.
I will also consider the environment with L5.15.32+. Thank you for your answer!
