One very common use case is a permanent storage space for the workloads that are deployed in each environment. Finding the original ODE using a solution. Thanks for contributing an answer to Ask Ubuntu! and Directories Within a File System, Changing file system object The sudo/root user can only modify the ownership of a file. whether the UID for the user is the same or different on those instances you see different The chown command in Linux allows you to change the ownership of files and directories. rw indicates that the filesystem is mounted read-write, ro indicates read-only.

This solution worked well for us since EKS version 1.14 all the way up until recently when we started moving customers to 1.21 and beyond. Amazon EFS behaves like a In our original implementation of EFS workloads in EKS, we started out using the (now retired) EFS provisioner. Several solution exists, some among them: you have a filesystem does not lets you eg. I added some counters (not posted) to the drivers to observe their behavior. Digging in even deeper to EKS and EFS specifically, we discovered that dynamic provisioning (which is what we rely on to provide a seamless, fast, efficient service for workloads) was recently added to the new CSI driver. Applications using the access point can only access data in its own directory and below.

An access point applies an operating system user, the NFS client. you'll want to either launch the mongo container as root, so that you can chown the directory, or if the image prohibits it (as some images already have a user mongo clause that prohibits the container from escalating privileges back up to root ), then one of two things: supersede the user with a securitycontext stanza in containers: or use an How to install WordPress on Linux without root privileges? image.png. Without going too far down the pros and cons of each storage system, we found that most customers were well satisfied with using Elastic FileSystem (EFS) mount points to provide persistent storage volumes backing the application workloads deployed to their clusters.

Internally mongo will create /data/db. behavior, as follows: If the user IDs are the same on both EC2 instances, Amazon EFS considers them to indicate Open the Terminal app and run the previous command.
