Codiusd (Codius Daemon) is the server-side component of Codius
Codius is an open-source decentralized hosting platform using Interledger. It allows anyone to run software on servers all over the world and pay using any currency. Users package their software inside of containers. Multiple containers can run together inside of a pod.
Codiusd (Codius Daemon; this software) is the server-side component. You can run one or more codiusd hosts in your datacenter and Codius clients will pay you to run their software. Codiusd uses hyperd to provide hardware-level isolation between different pods.
- CentOS 7 or higher
- Node.js 10 or higher
- A processor with virtualization support
First, you need to install hyperd. Once hyperd is installed, please make sure it is working correctly:
sudo hyperctl run -t hello-world
$ sudo hyperctl run -t hello-world
Using default tag: latest
latest: Pulling from library/hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

If you don't see the "Hello from Docker!" message, please troubleshoot your hyperd installation before proceeding.
Once hyperd is installed and working, you can install Codius Host.
sudo npm install -g codiusd
- Type: Integer
- Description: A monthly rate the host charges (in XRP) to host a program.
Codiusd
calculates this value down to the rate per second, as uploads are given a time in seconds to be hosted for. - Default: 10
- Type: String
- Description: The absolute path to the
hyperd
socket. - Default:
/var/run/hyper.sock
- Type: Boolean
- Description: Noops all
hyperd
API calls. - Default: false
- Type: Number
- Description: The port that codiusd will listen on.
- Default: 3000
- Type: String
- Description: The public URI resolving to this instance of codiusd.
- Default:
http://local.codius.org:CODIUS_PORT
- Type: Number
- Description: Amount of memory to allocate to codiusd for hosting.
- Default: 0.75
- Type: Boolean
- Description: Gives info about the host such as uptime, contracts currently running, monthly fee, etc. You can view this info at the /info endpoint, e.g.
codius.example.com/info
- Default: true
- Type: JSON Array
- Description: List of peers whose values are the URIs that resolve to their Codius instance.
- Default: [ ]
Create a pod that runs a given Codius Manifest and purchases the amount of time that the host will run it using Interledger
- Type: Object
Field Name | Type | Description |
---|---|---|
manifest | Object | An object containing a manifest for your code. The format can be found here. |
private | Object | An object containing private variables you want to pass to the host, such as an AWS key. An example can be found as part of the manifest format here. |
- Type: Object
Field Name | Type | Description |
---|---|---|
url | string | A URL resolving to the ip address of the pod that was just created. It is comprised of the pod's manifest hash followed by the hostname of the codius host. |
manifestHash | string | The hash of the manifest that was passed to the Codius host. |
expiry | string | A timestamp of when the pod will expire. |
- Variables:
duration
: Time in seconds for the Codius host to run your code. Makes an Interledger payment to buy the requested amount of time. Required.
Retrieve the most recent data in the standard output of a running pod, as specified by MANIFEST_HASH
.
NOTE: Only pods whose manifests contain debug: true
in their manifest
objects will be compatible with this endpoint.
-
Type: Stream
-
Description: A stream containing the most recent data written to the standard output of a given pod.
-
Variables:
follow
: A boolean value that, when set to true, will continue to follow the output of the specified pod's standard output in real time.
Returns the peers currently known to this host.
- Type: Array[String]
- Description: An array of size 10 containing peers known to the Codius Host.
Queries other Codius hosts for the peers known to each of them.
- Type: Object
Field Name | Type | Description |
---|---|---|
peers | Array[string] | An array of URIs of Codius hosts to query for additional peers. |
- Type: Object
Field Name | Type | Description |
---|---|---|
name | string | Name of the implementation of Codius that the host is running. In this case it is 'Codiusd (Javascript)' |
version | string | The version of Codiusd that the host is running, as described in package.json . |
peers | Array[string] | An array of peers known to the set of queried Codius hosts. |
- Type: Object
Field Name | Type | Description |
---|---|---|
name | string | Name describing the name of the Codius implementation that the host is running. In this case it is 'Codiusd (Javascript)' |
version | string | The version of Codiusd that the host is running, as described in package.json . |

See:
The hyperd logs will have errors like:
E0605 ... persist.go:100] Pod[...] failed to load inf info of : leveldb: not found
As a temporary workaround, offending containers can be removed from /var/lib/hyper/containers/
, which will allow them to be started again fresh.
