Introduction

Kata Containers currently supports packages for many distributions. Tooling to aid in creating these packages are contained within this repository.

Build using OBS

See the OBS documentation.

Build in a container

Kata build artifacts are available within a container image, created by a Dockerfile. Reference DaemonSets are provided in kata-deploy, which make installation of Kata Containers in a running Kubernetes Cluster very straightforward.

Build a snap package

See the snap documentation.

Build static binaries

See the static build documentation.

Build Kata Containers Kernel

See the kernel documentation.

Build QEMU

See the QEMU documentation.

Test Kata using ccloudvm

See the ccloudvm documentation.

Create a Kata Containers release

See the release documentation.

Jenkins files

See the Jenkins documentation.

Packaging scripts

See the scripts documentation.

Credits

Kata Containers packaging uses packagecloud for package hosting.

packaging's Issues

packaging CI is broken.

The CI is timing out:
The dockerfile used to build pkgs hangs more than 20 minutes trying to install some basic packages.

 RUN zypper -n install osc-plugin-install vim curl bsdtar git sudo pcre-tools

kernel: config: Improve CI for kernel config changes

There is two part in this issue.

Keep kernel config in sync
We need to maintain the kernel configs consistent between each other (across architectures) because we already have some discrepancies about some components that are not architecture specific. I am not sure how we can maintain some sort of synchronization across archs and which tool already exist for this, but we need this if we want to make sure we'll have Kata working consistently across x86, ARM and PPC.

Validate kernel config changes
We need the CI to run some specific check when modification are done to the kernel/config directory. This means every time a config gets modified, it should try to build the kernel with this config and then recreate an image to perform a sanity check (or maybe the full CI ???) that Kata Containers still work as expected. And to go one step further, we would need specific CI jobs to trigger the same tests for ARM and PPC configs on the appropriate worker VMs, so that we try on the appropriate arch. Maybe a simple way to bypass the complexity of having several worker VMs with different architectures would be to use cross compilation (but this means we can only try the build, we couldn't test Kata after this).

Automate the assets update for kata deploy.

Kata deploy require static binaries being published.

Instead of build it manually and upload with the github page automate the process of build all componets and push the assets to github.

Automate the gihub release creation

Today github releases are done manually after new release tags are created.

Automate the process to go to each repository and create a new github release based in a tag.

Add scripts to automate packing process for kata-containers

Add scripts to build packages to be build with OBS. Add support to build and package the following:

• runtime
• proxy
• shim
• agent(inside an guest os)
• linux kernel
• qemu lite

The packaging tools need support for local build and publish a build on OBS servers.

The packages tools could be build to point to a github commit or a tag.

pkg: kernel: Update kernel config name to x86_64 from x86

Update the name of kernel config file from x86 to x86_64 in update.sh

Build and artifact storage for kata containers

In Clear Containers, OBS was used for handling the packaging needs. This had a number of draw backs. Need to come up with solution and plan for meeting our packaging needs in Kata.

Add kernel configs and patches

Add the configs and patches needed in kata containers

Fedora packaging and QEMU forks

So, I've taken up packaging kata containers for Fedora. I'm looking at qemu-lite and qemu-vanilla packages. So, IIUC, those are forks of QEMU, correct?

Have we checked to see if the default 'qemu' package could be used/extended to suit kata containers?
Just that forking sounds like trouble unless real good reason.

(I'm both a QEMU and a Kata n00b, and I'll probably have more questions as we go, so please be gentle :) )

Following installation guide qemu is not installed in ubuntu

Following installation guide qemu is not installed in ubuntu (kata-containers/documentation#61)

$ docker run -ti busybox sh
docker: Error response from daemon: OCI runtime create failed: /usr/share/defaults/kata-containers/configuration.toml: file /usr/bin/qemu-system-x86_64 does not exist: unknown.

Missing Arm64 guest kernel config file

As the Developer-Guide[1] mentioned, the progress of installing guest kernel images need a default kernel config file. But for Arm64 architecture, this config file is missing. In this case, the Arm64 users can't follow the guide to complete the installation of guest kernel.

disable fno-semantic-interposition when gcc version is older than 5.3

--fno-semantic-interposition qemu option can only be added if the gcc used to build it is 5.3 or newer.
On CentOS, we have gcc 4.8.5 and therefore, qemu cannot be built correctly.

Related: kata-containers/tests#305

Add CI jobs

We want to make sure the packaging scripts work every change, lets add jobs from azure.

Import qemu hypervisor configuration script from Clear Containers

qemu has a lot of build options. We should be using a script that all the packaging scripts call to ensure there is a single source of qemu build options.

Such a script already exists in Clear Containers but is not (yet) being used (see clearcontainers/packaging#46). We should consider importing it for Kata:

• https://github.com/clearcontainers/packaging/blob/master/scripts/configure-hypervisor.sh

Distribution support for Kata Containers packaging

Need to come up with list of distributions that should be supported for Kata's packaging.

Create Fedora 28 OBS packages

• kata-containers/ci#25
• kata-containers/documentation#63

kernel: config file for ppc64le is missing.

Create Linux kernel configuration script

As @sameo noted in kata-containers/linux#5 (comment), we should have a script that can generate a valid kernel configuration file.

The script will generate a valid .config kernel configuration file to be used by the kernel's build system.

However, the script will allow individual options and groups of options to be documented as the kernel's config file does not support comments (well, it does, but only for "commented out" / disabled CONFIG_ options).

Each group of config options in the script should document:

• Why it has been enabled.
• If there is any known impact (positive or negative) on boot speed / general performance.
• If there is any known impact (positive or negative) on memory density.

Should we provide multiple guest kernel config files?

Hi,

Currently, we provide only one guest kernel config file for users to install guest kernel images. Should we provide more kernel config files for users to select? For example, we can provide config files for recent releases. e.g., from 4.14 ~ 4.16
{arch}_kata_kvm_4.14.x
{arch}_kata_kvm_4.15.x
{arch}_kata_kvm_4.16.x
and
{arch}_kata_kvm_generic for latest upstream code?

@Pennyzct @jodh-intel @grahamwhaley

kernel config: enable all cgroups support

We have disabled some cgroups support in the kernel config. We need to enable all of them, or at least add:

• CONFIG_BLK_CGROUP
• CONFIG_CGROUP_PIDS
• CONFIG_CGROUP_NET_PRIO

The above three are needed in current agent as init.

kata-runtime package missing collect script

We need to add the collect script to the kata-runtime package:

$ dpkg -c /var/cache/apt/archives/cc-runtime_3.0.23+git.64d2226-27_amd64.deb|grep collect
-rwxr-xr-x root/root     11099 2018-04-02 19:27 ./usr/bin/cc-collect-data.sh
$ dpkg -l kata-runtime|grep ^ii
ii  kata-runtime   1.0.0+git.086d197-39 amd64
$ dpkg -L kata-runtime|grep collect
$

Fix CI workflow

Currently, the Jenkins job of this repository shows that the CI passes correctly, but when digging into the console output, there are some errors:

Go not installed using amd64 to install go in dockerfile
+ PROJECT_REPO=home:katacontainers:release/qemu-lite

++ out=

++ echo 'ERROR: failed to checkout:'

++ exit 1

We need to investigate why this error does not make the CI job to fail.

bootstrap repo by importing Clear Containers packaging scripts

Now that Kata can be built and run we need to start thinking about building packages.

It probably makes sense to import https://github.com/clearcontainers/packaging with adjustments for Kata.

For the time being, we should also consider how best to deal with having two different runtimes. I suspect a virtual kata-runtime package would make sense which can depend on either kata-runtime-cc or kata-runtime-runv.

Add standard project files

Bootstrap the repo by adding the standard:

• Code of Conduct doc.
• Contributing doc.
• pullapprove config file.

kernel: Rename x86 config file to match tests/.ci/kata-arch script

Given that the kata-arch script returns x86_64 as arch on intel, we should rename the kernel config file to x86_64_kata_kvm_4.14.x

redhat: OBS: Qemu does not build in OBS with librados as requeriment.

Trying to build qemu in OBS fails because librados is not found.

release: Add script to automatically bump projects

Today every Kata release someone has to clone each repo increase the release number and do a PR.

To reduce the overhead we should have an script that does this (and potentially be triggered by the CI).

./send-new-kata-version-pr <VERSION>

Add CI for kernel changes

Add a job for jenkins that builds the kernel and runs the CI test to verify the config and patches works.

\cc @chavafg @devimc

packaging test in CI hangs more than 20 minutes in docker build

The packages in CI are build using a dockerfile the dockerfile takes more than 20 minutes in a single installation step. We need to find out the rootcause why is takaing a long time and re-enable tests.

Handle migration from Clear Containers / runv to kata containers

Once #1 is closed, we need to consider how to upgrade a system installed with either:

• Clear Containers
• runv

... and allow users to run the appropriate packaging command to upgrade to Kata.

For example, if Clear Containers is installed on an Ubuntu system, the following should install all required Kata components and remove the Clear Containers ones:

$ sudo apt-get install kata-runtime-cc

ppc64le: Generate packages for Kata Containers components

packages: Add OBS rhel packages

Enable rhel repositories to build kata packages.

configure-hypervisor: Add option to generate configuration for static qemu

https://github.com/egernst/kata-deploy requires to an static qemu to easily deploy kata. Lets add a static qemu configuration and a dockerfile to built it.

qemu: disable-static option not supported for qemu 2.11

Qemu 2.11 does not support --disable-static flag, we should remove it from scripts/configure-hypervisor.sh

Add a kata config version file to track the kernel changes

pkgs: Move obs scripts to its own directory.

This repository is growing is due to different things living here, kernel config and patches, obs scripts, kata-deploy, release tools.

Lets move the obs scripts to its own directory.

create script to validate kernel options across architectures

As we now support multiple architectures and each architecture requires a kernel config file, we need a way to ensure that all the architecture config files contain the "minimal" set of config options that will allow a Kata Container to be created.

There is bound to be some variation in config options for each architecture, but we need a way to be able to see those changes easily so they can be validated (as PRs are raised to update the kernel configs for example).

configure-hypervisor.sh: Add option get configuration for an static build

Add an new option to get the flags needed to build an static qemu.

Also provide a dockerfile to generate the static qemu.

Fix hypervisor config script

#12 had a couple of issues:

• doesn't include the security: tag for the static config option.
• makes use of unset variables (${qemu_version_major} and ${qemu_version_minor}).

Tag packaging repository after release

When a release is done tag the repository to know what scripts and kernel config was used to build kata packages.

Package bash completion code

Once kata-containers/runtime#378 lands, we'll need to update:

• https://github.com/kata-containers/packaging/blob/master/runtime/kata-runtime.spec-template

... by adding in code like we used to have in the Clear Containers packaging repo to handle the bash completion file:

• https://github.com/clearcontainers/packaging/blob/master/runtime/cc-runtime.spec-template

/cc @raravena80.

Add kernel config version to package version

#44 adds a new version to identify if a package has the latest configuration and patches needed by kata.

After it is merged we need to update the package creation scripts to add that version to the kernel pkg.

Build all go packages using same go version as CI

We need to ensure that when building golang packages we use the standard go version defined in the versions database.

Once kata-containers/runtime#114 lands, this will be queryable using:

$ go get -d github.com/kata-containers/runtime
$ cd $GOPATH/src/github.com/kata-containers/runtime
$ go get github.com/mikefarah/yq
$ yq read versions.yaml languages.golang.version
1.8.3

Related:

• #1
• clearcontainers/packaging#257

hypervisor config

Hypervisor config script uses some options only in newer bash versions.

This fails silently in centos leading to build a qemu without all options we want.
