Huginn: updating the docker image

[vijayrajah]

I have a docker based instance of huginn running on my server.

How do i update the image. I mean, If i do a "docker pull" will that remove the existing and initialize an new on?..

What is the official method of updating docker images.

I would love to know this too :)

docker pull will only update your local huginn image. To update the container your need to run docker stop, docker rm, and docker run to create a new container based on the updated image. Keep in mind that this will remove the data inside the old huginn container, when you are not using a linked database or exported the data using a volume.
When you are using docker-compose this will update to the latest version:

docker-compose stop
docker-compose pull
docker-compose up -d

Yes, Thanks for this @dsander .. I was running an instance which did not have mysql volume exported..
@johnnyzen
This is what i did

• Take a backup -- docker export -o ~/huginn.tar
• Find the volume for the current huginn image -- use docker inspect " and find the fs path for the container
• do an rsync of the volume to a directory on the docker_host (i used: rsynv -avp ..)
• stop the container -- docker stop
• remove the container -- docker rm
• get the latest code -- docker pull
• Instantiate a new container with the latest code -- docker exec -v "<>":/var/lib/mysql
  
  
  
  • I passed several environment variables like
  
  

-e DO_NOT_SEED=1 \
-e APP_SECRET_TOKEN="<>" \
-e TWITTER_OAUTH_KEY=<> \
-e TWITTER_OAUTH_SECRET=<> \
-e TIMEZONE="<>" \

Hope this helps

I believe that this issue has been resolved and can be closed -- not sure who closes it though.
