Lately I’ve been encountering some errors that, after some research, I discovered that the resolution was to upgrade my runc version. Since searching for upgrade runc did not yield any results I’ve decided to write this quick guide.
First verify your current runc version:
$ runc --versionMine was:
runc version 1.0.0-rc10
commit: dc9208a3303feef5b3839f4323d9beb36df0a9dd
spec: 1.0.1-devHow to upgrade?
Generally you have two options:
- Use the official
runcreleases binary file, found here. - Build
runcfrom the source code, which is the procedure I’ll cover in this post.
The instructions might change over time, so the official ones can be found here. I’ll list down the steps I took.
Building and upgrading runc from source code
runc currently supports the Linux platform with various architecture support. It must be built with Go version 1.13 or higher.
In order to enable seccomp support you will need to install libseccomp on your platform. On Ubuntu this can be done with:
$ sudo apt-get update -y
$ sudo apt-get install -y libseccomp-devNavigate to your $GOPATH/src directory:
$ cd $GOPATH/srcCreate the following directory:
$ mkdir github.com/opencontainersAnd run these commands:
$ cd github.com/opencontainers
$ git clone https://github.com/opencontainers/runc
$ cd runc
$ make
$ sudo make installrunc will be installed to /usr/local/sbin/runc on your system.
Notes:
- If you encounter errors on the
sudo make installcommand then it most likely since you are missing some packages. The output command should include the missing package name, simply install the missing package withapt-get install.
Validate your runc version:
$ runc --version
runc version 1.0.0-rc92+dev
