The problem come when we using Kubernetes, beasuse Kubernetes use Unconfined as default and disables seccomp filtering.įor example Docker’s default seccomp profile disables approximately 44 system calls of the 300+ currently availble. All container runtimes ship with a default seccomp profile. Usage of seccomp profiles on containers reduces the chance that a Linux kernel vulnerability will be exploited. It allow to create profiles to filter system calls. Seccomp (Secure Computing) is a feature in the Linux kernel. This means that seccomp filtering is disabled. By default, when Kubernetes makes a new container it creates with Unconfined seccomp profile. With Kubernetes version v1.22 there is a new alpha feature that provides a way to use the RuntimeDefault as the defaut seccomp profile insted of Unconfined.

The above command runs the image with name myimage and also maps the TCP port 80 to container port 8080. Run On Specific Port docker run -name myimage -p 80:8080 node:latest Let us assume our image “ node:latest” is configured to use port 8080 and we want to run the image using TCP port 80. Now, let us see how to instruct docker image to use a specific port. The above command will run the image with a name “ myimage“. Syntax – Docker Run Image docker run -name myimage node:latest Assume we have a docker image node:latest, take a look at the below command.

Do a ls command to list all the images and identify the name and tag. Assuming you have docker images ready for running, let us find out the name and tag of the image that we want to use. It takes lots of options and parameters, however in this post we will see the basic things required to run a docker image. Docker uses “ run” command to run the image.
