从 debian 8 升级到 debian 9 后出现 Docker seccomp 错误

Question

docker run过程中出现以下错误和 docker build从 Debian 8 升级到 Debian 9 后:

ERROR: Service 'etherpad' failed to build: OCI runtime create failed: container_linux.go:344: starting container process caused "error loading seccomp filter into kernel: invalid argument": unknown

我在使用 --seccomp-profile:unconfined 运行容器时解决了这个问题但 build 不支持这个标志( https://github.com/moby/moby/issues/21105 )。我还尝试通过 daemon.json 将它传递给守护程序，但这在启动过程中导致错误。

内核支持已启用:

grep CONFIG_SECCOMP= /boot/config-$(uname -r)
CONFIG_SECCOMP=y

有谁知道如何解决它？非常感谢。

TLDR； 升级到 Stretch 后重启服务器。

您的问题看起来与我遇到的问题相似。我收到以下错误:

OCI runtime create failed: container_linux.go:345: starting container process caused "error loading seccomp filter into kernel: invalid argument": unknown

从 Jessie 升级到 Stretch 并安装 Docker 的全新副本 ( https://docs.docker.com/install/linux/docker-ce/debian/ ) 后，出现此问题。

我相信你的问题是相似的，因为你的 docker info 输出显示

Kernel Version: 3.16.0-7-amd64

对我来说:

# uname -a
Linux debian 3.16.0-7-amd64 #1 SMP Debian 3.16.59-1 (2018-10-03) x86_64 GNU/Linux

Stretch 应该使用比那个更高的内核版本，所以修复是:

# reboot
# uname -a
Linux debian 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u2 (2019-05-13) x86_64 GNU/Linux
