Arvados-in-a-box

Arvbox is a Docker-based self-contained development, demonstration and testing environment for Arvados. It is not intended for production use.

Quick start

$ git clone https://github.com/arvados/arvados.git
$ cd arvados/tools/arvbox/bin
$ ./arvbox start localdemo
$ ./arvbox adduser demouser demo@example.com

You can now log in as demouser using the password you selected.

Install root certificate

Arvbox creates root certificate to authorize Arvbox services. Installing the root certificate into your web browser will prevent security errors when accessing Arvbox services with your web browser. Every Arvbox instance generates a new root signing key.

Export the certificate using arvbox root-cert
Go to the certificate manager in your browser.
- In Chrome, this can be found under “Settings → Advanced → Manage Certificates” or by entering chrome://settings/certificates in the URL bar.
- In Firefox, this can be found under “Preferences → Privacy & Security” or entering about:preferences#privacy in the URL bar and then choosing “View Certificates…”.
Select the “Authorities” tab, then press the “Import” button. Choose arvbox-root-cert.pem

The certificate will be added under the “Arvados testing” organization as “arvbox testing root CA”.

To access your Arvbox instance using command line clients (such as arv-get and arv-put) without security errors, install the certificate into the OS certificate storage (instructions for Debian/Ubuntu):

copy arvbox-root-cert.pem to /usr/local/share/ca-certificates/
run /usr/sbin/update-ca-certificates

Configs

dev

Development configuration. Boots a complete Arvados environment inside the container. The “arvados” and “arvados-dev” code directories along data directories “postgres”, “var”, “passenger” and “gems” are bind mounted from the host file system for easy access and persistence across container rebuilds. Services are bound to the Docker container’s network IP address and can only be accessed on the local host.

In “dev” mode, you can override the default autogenerated settings of Rails projects by adding “application.yml.override” to any Rails project (api, workbench). This can be used to test out API server settings or point Workbench at an alternate API server.

localdemo

Demo configuration. Boots a complete Arvados environment inside the container. Unlike the development configuration, code directories are included in the demo image, and data directories are stored in a separate data volume container. Services are bound to the Docker container’s network IP address and can only be accessed on the local host.

test

Starts postgres and initializes the API server, then runs the Arvados test suite. Will pass command line arguments to test runner. Supports test runner interactive mode.

devenv

Starts a minimal container with no services and the host’s $HOME bind mounted inside the container, then enters an interactive login shell. Intended to make it convenient to use tools installed in arvbox that don’t require services.

publicdev

Publicly accessible development configuration. Similar to ‘dev’ except that service ports are published to the host’s IP address and can accessed by anyone who can connect to the host system. See below for more information. WARNING! The public arvbox configuration is NOT SECURE and must not be placed on a public IP address or used for production work.

publicdemo

Publicly accessible development configuration. Similar to ‘localdemo’ except that service ports are published to the host’s IP address and can accessed by anyone who can connect to the host system. See below for more information. WARNING! The public arvbox configuration is NOT SECURE and must not be placed on a public IP address or used for production work.

Environment variables

ARVBOX_DOCKER

The location of Dockerfile.base and associated files used by “arvbox build”.
default: result of $(readlink -f $(dirname $0)/../lib/arvbox/docker)

ARVBOX_CONTAINER

The name of the Docker container to manipulate.
default: arvbox

ARVBOX_BASE

The base directory to store persistent data for arvbox containers.
default: $HOME/.arvbox

ARVBOX_DATA

The base directory to store persistent data for the current container.
default: $ARVBOX_BASE/$ARVBOX_CONTAINER

ARVADOS_ROOT

The root directory of the Arvados source tree
default: $ARVBOX_DATA/arvados

ARVADOS_DEV_ROOT

The root directory of the Arvados-dev source tree
default: $ARVBOX_DATA/arvados-dev

ARVBOX_PUBLISH_IP

The IP address on which to publish services when running in public configuration. Overrides default detection of the host’s IP address.

Using Arvbox for Arvados development

The Arvbox section of Hacking Arvados has information about using Arvbox for Arvados development.

Making Arvbox accessible from other hosts

In “dev” and “localdemo” mode, Arvbox can only be accessed on the same host it is running. To publish Arvbox service ports to the host’s service ports and advertise the host’s IP address for services, use publicdev or publicdemo:

$ arvbox start publicdemo

This attempts to auto-detect the correct IP address to use by taking the IP address of the default route device. If the auto-detection is wrong, you want to publish a hostname instead of a raw address, or you need to access it through a different device (such as a router or firewall), set ARVBOX_PUBLISH_IP to the desire hostname or IP address.

$ export ARVBOX_PUBLISH_IP=example.com
$ arvbox start publicdemo

Note: this expects to bind the host’s port 80 (http) for workbench, so you cannot have a conflicting web server already running on the host. It does not attempt to take bind the host’s port 22 (ssh), as a result the arvbox ssh port is not published.

Notes

Services are designed to install and auto-configure on start or restart. For example, the service script for keepstore always compiles keepstore from source and registers the daemon with the API server.

Services are run with process supervision, so a service which exits will be restarted. Dependencies between services are handled by repeatedly trying and failing the service script until dependencies are fulfilled (by other service scripts) enabling the service script to complete.
