QUESTION
For the current working scenario I have two containers which need to share data. First container is a flask application which does some work on data and creates log file. While the other container is R shiny app which serves as a status dashboard for the application, and also when needed user can also directly view the log file by providing a key on the dashboard itself. Here my issue is that while accessing log file from shiny dashboard container permission denied error is being thrown. I have mounted same volume on both the containers also tried giving owner permission to shiny app container but still container could not access the file, while I can access the same file on host location. Is there something I am missing which needs authorization of shared volumes among containers or is there is any issue with the shiny app. Please provide possible solutions to it.

Answered 2019-Feb-11 at 18:18When you have both image
and build
in a docker-compose service precedence is given to image
. In your scenario your since you have image: rocker/rstudio
in your compose file it will pull the rocker/rstudio:latest
image from docker-hub. But what do you want is a image build on top of the rocker/rstudio
image (In Dockerfile it has been used as the base image).
It is not a good practice to tag your image as with existing tag in docker-hub (You may face difficulties as wrong image is cached in your local docker images as you experienced here). First decide whether you really want to name your image (Otherwise compose will tag the image for you where tag include a part of your service name so you can easily identify). If you want use it as following with a prefix in image tag. Same goes with other two services.

I'm getting an error running bx dev build

ANSWER
Answered 2018-Jan-22 at 19:35Was there a reason that you were trying to run bx dev build
using sudo
? Did you run bx dev create
under sudo
also? This sounds like a permissions issue.
The error message is actually coming from Docker, not internal to the IBM Developer Tools executable:
OCI runtime exec failed: exec failed: container_linux.go:295: starting container process caused "process_linux.go:86: executing setns process caused \"exit status 22\"": unknown
