Deployment

Once on the server:

Create a new bridge network so that containers can find each other:

docker network create wikinet

Create the wiki-update-companion container:

docker run -d --name=wiki-update-companion -v /var/run/docker.sock:/var/run/docker.sock:ro --restart=unless-stopped -h wiki-update-companion --network=wikinet ghcr.io/ietf-tools/wiki-update-companion:latest

For each Wiki.js instance:

Create a container, replacing the following xyz123 values in the command below:

docker run -d --name=xyz123 -e DB_HOST=xyz123 -e DB_PORT=5432 -e DB_PASS=xyz123 -e DB_USER=xyz123 -e DB_NAME=wiki -e UPGRADE_COMPANION_REF=xyz123 -h xyz123 -p 80:3000 -v /xyz123/mappings.json:/wiki/server/modules/authentication/ietf/mappings.json:ro --network=wikinet --restart=unless-stopped ghcr.io/ietf-tools/wiki:latest

--name=xyz123 -> Name of the instance, should be unique for each container, e.g. --name=wiki-ietf
-e DB_HOST=xyz123 -> Hostname / IP of the PostgreSQL database server. (if database is on the host, see Database on Localhost below.)
-e DB_PORT=5432 -> Port of the PostgreSQL database server.
-e DB_USER=xyz123 -> Username to connect to the PostgreSQL database server.
-e DB_PASS=xyz123 -> Password to connect to the PostgreSQL database server.
-e DB_NAME=wiki -> Database name on the PostgreSQL server.
-e UPGRADE_COMPANION_REF=xyz123 -> Name reference to this container for the upgrade tool. Should be identical to the container name entered above (e.g. -e UPGRADE_COMPANION_REF=wiki-ietf).
-h xyz123 -> Hostname of the container instance. Should be identical to the container name entered above (e.g. -h wiki-ietf).
-p 80:3000 -> Change 80 to the desired port to expose. The port should be unique for each container. Do not change the 3000 value, this is the internal container port!
-v /xyz123/mappings.json:... -> Path on the server (host) to the mappings.json file. This file will be mounted into the container.
--network=wikinet -> Name of the bridge network created earlier.

Ensure the container started correctly by running (replacing xyz123 with the name of the container):

docker logs xyz123 -f

The output should include the line HTTP Server: [ RUNNING ]

Add the proper config to your reverse-proxy software (e.g. nginx / apache) to point each domain to the correct port you exposed above.
If this is a new Wiki.js instance, complete the setup by loading the domain name in your browser.

Database on localhost

Note that you cannot use localhost or 127.0.0.1 as the DB_HOST value to communicate to a PostgreSQL server installed on the host itself, as localhost refers to the container itself, not the host. You must instead add the following to the docker run command (note that there's nothing to replace in the command below, host-gateway is a special docker keyword!):

--add-host=host.docker.internal:host-gateway

This will add a DNS entry in the container that automatically points to the Docker host IP address. You can then specify host.docker.internal as the host for the DB_HOST parameter.

Modules

Authentication - IETF Datatracker

Note
The mappings.json provided in this repository is only an example and should be modified to match the target instance use case.

Initial Setup

Head to Wiki.js Administration Area and validate that all groups specified in mappings.json have been added under Groups. Missing groups are automatically created during initialization.
Still under Groups, add the necessary page rules / permissions for all groups.

Note that groups must NOT be renamed. They must match exactly as they are in mappings.json.
Under Authentication settings add the strategy IETF datatracker OpenID Connect
- Enable Allow self-registration
- Complete the configuration with the IETF provider settings
- Ensure that the machine is reachable to the strategy callback URL

Non-Docker Usage

Copy the whole ietf folder under the path server/modules/authentication/ of your wiki.js instance.

Mappings

The mapping between IETF datatracker roles and wiki.js groups can be specified in the mappings.json file. The format of the file is the following:

{
    "defaults": Array of Strings,
    "groups": Array of Strings,
    "mappings": Object
}

defaults contains the list of the groups that will be auto-added to any authenticated users, e.g.:

{
    "defaults": ["members", "users"],
    "groups": [],
    "mappings": {
        ...
    }
}

groups contains the list of the groups that will be automatically created if they don't already exist on initialization:

{
    "defaults": [],
    "groups": ["iesg", "ietf-chairs"],
    "mappings": {
        ...
    }
}

mappings has the following format:

{
    "defaults": ...
    "groups": ...
    "mappings": {
        "roles": {
            "groupname_1": Array of Arrays,
            "groupname_2": Array of Arrays,
            "groupname_3": Array of Arrays,
            ...
        },
        "dots": {
            "groupname_4": Array of Strings,
            ...
        }
    }
}

Any element of an array groupname in the roles section is a tuple [oidcRole, oidcGroup, ... ] (as returned by the datatracker OIDC user-info API) that will match the groupname wiki.js group, e.g.:

...
"mappings": {
    "roles": {
        "admins": [
            [
                "ad",
                "iesg",
                ...
            ],
            [
                "chair",
                "ietf",
                ...
            ],
        ],
        "iesg": [
            [
                "ad",
                "iesg"m
                ...
            ],
            [
                "execdir",
                "ietf",
                ...
            ]
        ],
        ...
    }
    ...
}

By using wildcards * you can omit any tuple element, e.g.:

"mappings": {
    "roles": {
        "chairs": [
            [
                "chair",
                "*",
                ...
            ]
        ],
        "iesg-users": [
            [
                "*",
                "iesg",
                ...
            ]
        ],
        ...
    }
    ...
}

Any element of an array groupname in the mappings dots section is an array of strings [dot1, dot2, ... ] (as returned by the datatracker OIDC user-info API) that will match the groupname wiki.js group, e.g.:

"mappings": {
    ...
    "dots": {
        "chairs": [ "llc", ... ],
        ...
    }
    ...
}

Any change to the mappings file requires a restart of the container while in dev mode.

Rendering - IETF Custom

This rendering module ensures that any references to RFC's or Internet Drafts are automatically linked to their corresponding Datatracker page.

This module should be enabled by default under the Administration Area > Rendering > HTML

Docker Dev Environment

docker-compose up
Complete the initial setup of wiki.js by connecting to http://HOST:PORT (default PORT is 1926)
Create a homepage
Head to wiki.js Administration settings and add the groups specified in mappings.json
Create the group rules if you need to enforce the permission system
Under Authentication, add the strategy IETF datatracker OpenID Connect
- Enable Allow self-registration
- Complete the configuration with the IETF provider settings
- Ensure that the machine is reachable to the strategy callback URL
