DODAS client

Installation and usage

Download the binary from the latest release on github. For instance:

wget https://github.com/DODAS-TS/dodas-go-client/releases/download/v1.3.0/dodas.zip
unzip dodas.zip
cp dodas /usr/local/bin

In alternative you can also run the dodas command inside the client container dodasts/dodas-client:v1.3.0.

CLI autocomplete

Autocompletion for bash and zsh is supported

• bash add the following line to ~/.bashrc: . <(dodas autocomplete)
• zsh add the following line to ~/.zshrc: source <(dodas zsh-autocomplete)

You can find now a template for creating your client configuration file in config/client_config.yaml. Note that by default the client will look for $HOME/.dodas.yaml.

Now you are ready to go. For instance you can validate a tosca template like this:

dodas validate --template tests/tosca/valid_template.yml

Tip: you can find supported tosca templates for applications and k8s deployments on the DODAS template repo

or you can create a cluster through the InfrastructureManager configured in your configuration file:

dodas create --config my_client_conf.yaml my_template.yaml

To list the Infrastructure ID of all your deployments:

dodas list infIDs

You can eventually login into a vm in created cluster that has a public IP address with:

dodas login <infID> <vmID>
# e.g. dodas login cb585e5c-33b6-11ea-8776-0242ac150003 0

Quick start

Your deployments will be created and managed by the InfrastructureManager(IM). To start playing with DODAS please refer to this two quick start guides on the official site:

• using the community instance of IM (required free registration for evaluation purpose here)
• a standalone setup where IM will be deployed in a docker container and used with the client

N.B All of the pre-compiled templates provided by DODAS use the helm charts defined and documented here.

Therefore all the available applications can be installed as they are on top of any k8s instance with Helm

Building from source

To compile on a linux machine (go version that supports go modules is required for building from source: e.g. >= v1.12):

make build

while to compile with Docker:

make docker-build

It's also possible to cross compile for windows and macOS with:

make windows-build
make macos-build
