Issue
"/etc/docker/daemon.json" "/etc/docker/daemon.json" E212: Can't open file for writing
I’m currently trying to set up a Loki server, Promtail, and Grafana as docker images
I installed all the plugins needed however when I tried editing the docker daemon config file with this command
sudo nano /etc/docker/daemon.json
It does not allow me to write due to permissions so I tried using
sudo vi chmod 666 /etc/docker/daemon.json
but this only creates a new file in my directory called chmod
The docker containers are up but I can't see the Loki metrics on my web browser when I try to use localhost:3100/metrics neither can it can be added as a Datasource
Please can you help?
Solution
It should be sudo chmod 666 /etc/docker/daemon.json.
What you are doing is running vi against 3 files, chmod, 666, /etc/docker/daemon.json.
The directory /etc/docker must also exist as a directory, and not as a file.
