# References - https://github.com/RocketChat/Docker.Official.Image # Notes The mongodb container will likely throw a permission error when bein started for the first time. ```` error: 'An error occurred when creating an index for collection "users: getaddrinfo EAI_AGAIN mongodb', reason: undefined, details: undefined, errorType: 'Meteor.Error' ```` Therefore, you have to adjust the permissions of the mongodb volume path. For example with the following command: ```` sudo chmod -R 777 /mnt/docker-volumes/rocketchat ````
