Analysis: the disk of k8s node node is full, which is usually caused by a container writing to the log, so you only need to find the corresponding node.

# one. Install the package ncdu (to prevent the impact of hard links)

Yum-y install ncdu

# II. View specific directories with large disk space

Through such a layer-by-layer search, it is found that the directory that caused the disk space to be full is

/ data/kubernetes/docker/overlay2/ba9d61214d6c065274161d7f0171e91001d209adce8f377b9bf698e18ec74713

Note: this directory is written in the inpsect of the container and can be found through the for loop.

three。 Locate the container id through the for loop

For i in docker ps | awk-F'[] +'{print $1}'; do echo $I & & docker inspect $I | grep'/ data/kubernetes/docker/overlay2/ba9d61214d6c065274161d7f0171e91001d209adce8f377b9bf698e18ec74713/merged';done

Once you find the id of the container, you will basically know which container caused it, and it will be easy to solve it later.
