Hey everyone,
I ran into a small issue today using docker-compose. I had a config file I was trying to mount as a volume however running “docker-compose up” generated a folder instead.
ERROR: for grafana Cannot start service grafana: OCI runtime create failed: container_linux.go:349: starting container process caused “process_linux.go:449: container init caused \”rootfs_linux.go:58: mounting \\\”/host_mnt/e/repos/Sample-Twitch/grafana/datasources.yml\\\” to rootfs \\\”/var/lib/docker/overlay2/f5c9553407551b68dc5d5877d748ba2bf7d2f0dd2ad12c73e39be40af185c82d/merged\\\” at \\\”/var/lib/docker/overlay2/f5c9553407551b68dc5d5877d748ba2bf7d2f0dd2ad12c73e39be40af185c82d/merged/etc/grafana/provisioning/datasources/prometheus.yaml\\\” caused \\\”not a directory\\\”\””: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type
ERROR: Encountered errors while bringing up the project.
The issue turned out to be an oversight on my part, I’d misspelled the config filename and docker was unable to find it. Consequently, it generated the missing file as a directory.
It took a bit of Googling to narrow this down, but eventually this stackoverflow post pointed me in the right direction: https://stackoverflow.com/a/44950494/522859
Thanks,
