Data loss with docker instructions

[axelson]

Is it expected that you would lose your data if you run via docker with docker run -it -p 3000:3000 huginn/huginn and close and restart the process.

Not directly, the README has this:

NOTE: If you do not export the volume, or use a separate database container, you cannot update Huginn without losing your data.

In your case the data isn't gone yet. docker ps -a should list your previous container and you can start it again using docker start <containerid>.

Ah, ok. I'm glad that my data still exists! I didn't notice that message when installing Huginn initially (and I want to work on a PR to update the installation instructions). Quick question, if I continue running Huginn with docker start <containerid> the data will be okay until I update Huginn?

And if I want to use the docker installation of Huginn with an already running external postgres instance is it just a matter of passing HUGINN_DATABASE_USERNAME, HUGINN_DATABASE_PASSWORD, and HUGINN_DATABASE_ADAPTER to the docker instance?

It will, but getting the data out of the container is not easy.

Yes, this should work:

docker run --rm --name huginn \
    -p 3000:3000 \
    -e DATABASE_USERNAME=huginn \
    -e DATABASE_PASSWORD=mysecretpassword \
    -e DATABASE_ADAPTER=postgresql \
    -e DATABASE_HOST=iporhostnameofpostgres \
    -e DATABASE_NAME=huginn \
    huginn/huginn
