Block Storage


DO Block Storage>

The DOBS plug-in can be installed with the following command:

$ docker plugin install rexray/dobs \
  DOBS_REGION=sfo2 \

The DOBS plug-in requires that your DigitalOcean droplet is running in a region that supports block storage.

NOTE: DigitalOcean volumes cannot be created if their name contains an underscore. Docker will automatically append prefixes with underscores to your volume names when they are created as part of a compose file, so if you're creating volumes with this plugin using compose (or stack deploy), be sure to set DOBS_CONVERTUNDERSCORES to true.


The DOBS plug-in requires the following privileges:

Type Value
network host
mount /dev
allow-all-devices true
capabilities CAP_SYS_ADMIN

The following environment variables can be used to configure the DOBS plug-in:

Environment Variable Description Default Required
DOBS_CONVERTUNDERSCORES Set to true if the plugin will create volumes at DigitalOcean via e.g. a docker-compose.yml file false
DOBS_REGION The region where volumes should be created
DOBS_STATUSINITIALDELAY Time duration used to wait when polling volume status 100ms
DOBS_STATUSMAXATTEMPTS Number of times the status of a volume will be queried before giving up 10
DOBS_STATUSTIMEOUT Maximum length of time that polling for volume status can occur 2m
DOBS_TOKEN Your DigitalOcean access token
HTTP_PROXY Address of HTTP proxy server to gain access to API endpoint
