# Realms Wiki Beta with LDAP support

This is a recipe of [Realms Wiki](https://github.com/scragg0x/realms-wiki) patched so that a docker image is build with LDAP support. The Dockefile actually downloads the Realms Wiki code from  [Matthew Scragg's](https://github.com/scragg0x) original repo and not from my fork.

### Differences from the master repo

* The docker image is based on Debian jessie instead of Ubuntu trusty
* The *flask_ldap_login* is patched using [Stephane Martin's](https://github.com/stephane-martin) [patch](https://github.com/ContinuumIO/flask-ldap-login/issues/26) to eliminate the "Internal Server Error" message when logging in with LDAP.

### Clone the repo

```
git clone git@github.com:theodotos/realms-wiki.git
```

### Build the image

```
cd realms-wiki/docker
docker build -t realm-wiki-img .
```

### Pull it from Docker Hub

If you prefer using my build, you can pull it from Docker Hub:

```
docker pull theodotos/realms-wiki
```

### Run the container

Create a *realms-wiki* volume:

```
docker volume create --name realms-wiki
```

For your own build:

```
docker run -d --name realms-wiki -p 5000:5000 --volume realms-wiki:/home/wiki realms-wiki-img
```

For my build:

```
docker run -d --name realms-wiki -p 5000:5000 --volume realms-wiki:/home/wiki theodotos/realms-wiki:latest
```

### Configure the container

Prepare a *realms-wiki.json* file like this:

```
cat > realms-wiki.json << EOF
{
    "ALLOW_ANON": true,
    "BASE_URL": "http://realms.example.com",
    "CACHE_TYPE": "simple",
    "DB_URI": "sqlite:////home/wiki/data/wiki.db",
    "PORT": 5000,
    "REGISTRATION_ENABLED": true,
    "SEARCH_TYPE": "simple",
    "SECRET_KEY": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "SITE_TITLE": "Example Wiki",
    "WIKI_PATH": "/home/wiki/data/repo",

    "LDAP": {
        "URI": "ldap://ldap.example.com:389",
        "BIND_DN": "cn=realms,ou=services,dc=example,dc=com",
        "BIND_AUTH": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        "USER_SEARCH": {
            "base": "ou=people,dc=example,dc=com",
            "filter": "uid=%(username)s"},
        "START_TLS": true,
        "KEY_MAP": {
            "username": "uid",
            "email": "mail"},
        "OPTIONS": {
            "OPT_PROTOCOL_VERSION": 3}
    }
}
EOF
```

**NOTE: you can use the `apg -n1 -x65 -m65` command to generate a SECRET_KEY**

Copy the config over to the container:

```
cp realms-wiki.json realms-wiki:/home/wiki/realms-wiki
```

Restart the container:

```
docker restart realms-wiki
```

Browse to http://realms.example.com:5000 to test it.

### Some tips about STARTTLS 

If you ldap backend is not protected by a publicly trusted CA, you will need to add your Internal ROOT CA certificate in the trusted CA list of your container.

Copy your Internal ROOT CA certificate in the container:

```
docker cp example-rootca.crt realms-wiki:/usr/local/share/ca-certificates/
```

Add your Internal CA as trusted in the trusted CA list:

```
docker exec -i -t -u root realms-wiki /usr/sbin/update-ca-certificates
```

Restart the container and try again.
