Installation
Driver can be installed several ways
From source code
(Requires Go 1.13+, gcc and make installed)
- Clone this git repository to any location
- Run
make build && sudo make install, driver for linux will be built and copied to/usr/local/bin
Using built binary
An already built driver for both Linux and Windows distributions can be found in releases section.
You will have to copy driver to directory in $PATH so docker-machine would be able to find it.
Usage
docker-machine-opentelekomcloud can be used either as Rancher node driver or as stand-alone Docker Machine driver.
Stand-alone
OpenTelekomCloud driver processes existing clouds.yaml files to authenticate in OTC.
Having otc cloud in your clouds.yaml, creating of docker-machine is as easy as running.
$ docker-machine create -d otc --otc-cloud otc defaultFollowing will be created if not provided:
- Security Group:
docker-machine-grp - VPC:
vpc-docker-machine - Subnet:
subnet-docker-machine - Elastic IP: with bandwidth limited to
100MBit/s
Machine with following setup will be started:
- Flavor:
s3.xlarge.2 - Image:
Standard_Ubuntu_20.04_latest - Volume Size:
40GB - Volume Type:
SSD
Removing machine will remove all resources created on machine creation.
