How to configure the redis plugin to run a custom docker image for the install #43

Closed erikschlegel closed 8 years ago

erikschlegel commented 8 years ago

I have a custom image thats using the redis release candidate version 3.2, which supports geospatial indexes. How do I configure the redis plugin to use a different image not included in the https://hub.docker.com/r/library/redis/tags/ ? Tried changing the REDIS_IMAGE_VERSION and REDIS_IMAGE vars but I received a Redis image x:y not found'.

All the best,

Erik

What did you set those values to, and what was the exact message?

You will also need to pull that image down.

thanks for the response. I'm setting the 2 variables to the following. Just an FYI, I'm still learning the ropes to both redis and dokku.

export REDIS_IMAGE="erikschlegel/redis-rc" export REDIS_IMAGE_VERSION="3.2.0"

When I try and create a new redis service I receive the following statement.

dokku redis:create guidedogs-cache-service

% Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 45390 100 45390 0 0 208k 0 --:--:-- --:--:-- --:--:-- 209k -----> Starting container Waiting for container to be ready

I'm not able to pass this message.

Appreciate your help.

All the best,

Erik

Does your image work in the same fashion as the official redis image? If not, then the waiting section may fail.

It seems to start with no issues. I included the output below.
