[Docker] How to solve the error function not implemented @ io_fread ~ [Super easy]
Let's start with the solution
Just restart the Docker desktop app! !!
That was all, what was the time so far ... With Docker for Window, right-click the whale icon at the bottom right and press Restart. (See image ↓)
Background of the error
When I built a new Docker environment to run the Rails application cloned from github and played around with it, for some reason the Docker container that was working normally in other projects suddenly stopped starting.
【environment】
- windows10 Pro
- Rails: 6.0.3.2
- ruby: 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]
- Docker for windows
- MySQL 5.7
- nginx:1.15.8
error contents
・ ・ ・ (Omitted) Function not implemented@ io_fread (directory or file name)
I was impatient with an error I had never seen. It was the beginning of hell that I wondered why the Docker container, which is a virtual environment, would not affect other containers, and messed with the Dockerfile. You couldn't isolate the cause at all.
Thank you for watching until the end.
I hope it helps you to solve the error! !!
