mv: missing destination file operand after ‘/var/lib/docker/volumes/postgresql-foo’ about dokku-pg-plugin HOT 19 CLOSED

Digged into the commands file and seems like $VOLUME_PATH is empty when it tries to rename the container.

Sadly I don't have time nor dokku instance to test it right now. It may be caused by a recent pull-request or by a dokku update.

@Kloadut, that's ok. I'll look into it when I have more time.

Some more information, I was using Digital Ocean with the Ubuntu 13.04 x64 Image doing a fresh install of Dokku. I'm guessing it's being caused by $VOLUME_PATH not being set by this line: https://github.com/Kloadut/dokku-pg-plugin/blob/master/commands#L57 thus getting the missing destination file operand.

I'm currently using Digital Ocean and recommend others (using Digital Ocean) to use the 1-Click Installer (instructions here: http://goo.gl/MfMrGR), this plugin works fine with the 1-Click Installer.

We have been trying to install a postgresql database with dokku-pg-plugin for two days and we have encountered the same issue. We looked a bit into the code and found the same line. I don't know if it helps but it seems like "/var/lib/docker/volumes" is no longer presented in the output of the "docker inspect" command. The VOLUME_PATH hence is empty.

As we don't know anything about docker we have naively tried to work with a downgraded version (0.6.7) with apt-get but it lead to another error "PostgreSQL image not found... Did you run 'dokku plugins-install' ?"

If anyone has knowledge about docker, his/her help would be greatly appreciated.

from dokku-pg-plugin.

@gchelfi, yes I ran 'dokku plugins-install' after cloning this repo into /var/lib/dokku/plugins.

@gchelfi can you let us know a bit about your environment setup?

from dokku-pg-plugin.

@mpbod We are working on Ubuntu 13.04 and have installed stable dokku (0.2.0) from their github repo. We have installed Postgresql 9.1. dokku-pg-plugin is the only plugin we have installed.

from dokku-pg-plugin.

@gchelfi, I'm not sure if this is will help but here's the environment Digital Ocean provides with their 1-Click Installer in which dokku-pg-plugin works:

Ubuntu 13.04 x64
Docker version 0.6.6, build 6d42040
dokku v0.2.0-RC3

I just followed the instructions in this repo to install it.

Hope it helps.

BTW. You won't need to install Postgresql, this plugin will install in the docker containers.

from dokku-pg-plugin.

From what I see the result of docker inspect from a clean install of dokku is different from older version, 0.6.6 in my case, making parsing of VOLUME_PATH not possible (docker inspect returns blank), Ref: https://github.com/Kloadut/dokku-pg-plugin/blob/master/commands#L57

the plugin tries to grep this output for /var/lib/docker/volumes which as you can see doesn't exist.
I'm not sure if this is just a matter of changing how the value for VOLUME_PATH is looked up, or if it's some larger issue, but i don't think i have enough experience with these tools to fix it myself right now

See #8 but it doesn't solve the bigger issue of getting this to work again.
