Edit the host machine /etc/hosts file Add 127.0.0.1 host.docker.internal

╭─ ~ ─────────────────────────────────────────────────────────────────── ✔ ─╮ ╰─ ping host.docker.internal ─╯ ping: cannot resolve host.docker.internal: Unknown host

Host Database

localhost is used to configure the loopback interface

when the system is booting. Do not change this entry.

127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost 127.0.0.1 host.docker.internal

Added by Docker Desktop

To allow the same kube context to work on the host and the container:

127.0.0.1 kubernetes.docker.internal

Rationale: You cannot set memory in container.

in ~/.kube/config change the 0.0.0.0 to host.docker.internal
