What happened

Whenever I reboot my computer, /etc/hosts entries added by Devcontainer are gone

devcontainer up --workspace-folder .
devcontainer exec --workspace-folder . /bin/bash
cat /etc/hosts

#127.0.0.1	localhost
#::1	localhost ip6-localhost ip6-loopback
#fe00::0	ip6-localnet
#ff00::0	ip6-mcastprefix
#ff02::1	ip6-allnodes
#ff02::2	ip6-allrouters
#172.17.0.1	host.docker.internal
#172.17.0.2	be7abe611b1c
#127.0.0.1 dex
#127.0.0.1 minio
#127.0.0.1 postgres
#127.0.0.1 mysql
#127.0.0.1 azurite

reboot
devcontainer up --workspace-folder .
devcontainer exec --workspace-folder . /bin/bash
cat /etc/hosts

#127.0.0.1	localhost
#::1	localhost ip6-localhost ip6-loopback
#fe00::0	ip6-localnet
#ff00::0	ip6-mcastprefix
#ff02::1	ip6-allnodes
#ff02::2	ip6-allrouters
#172.17.0.1	host.docker.internal
#172.17.0.2	be7abe611b1c

What I expect

/etc/hosts should be preserved

Why it happens

That's Because Devcontainer's container is running with bridge networking

How to fix It

https://code.visualstudio.com/remote/advancedcontainers/start-processes
Add postStartCommand field that adds /etc/hosts entries to devcontainer.json
Add --add-host options as runArgs in devcontainer.json
