You can configure your cozy-stack
using a configuration file.
By default, cozy-stack
comes with a file named cozy.example.yaml
.
If you need to edit the configuration, we recommend to only copy the
needed part in a new file. This new file should be named cozy.yaml
,
cozy.yml
, or cozy.json
depending on the format of your chosing,
and should be present in one of these directories (ordered by priority):
./.cozy
$HOME/.cozy
/etc/cozy
The path of the configuration file can also be define from an absolute path
given by the --config
(or -c
) flag of the cozy-stack command.
Note that is is possible to have an additional configuration file, with the
.local
suffix. For example, it can be used to have /etc/cozy/cozy.yml
managed by a package manager, and /etc/cozy/cozy.yml.local
for things that a
user can customize.
It is possible to pass environnment variable to this configuration using the
template language of golang, delimited
by {{
and }}
.
The environment variables are available in the .Env
variable. For instance the
text {{.Env.COUCHDB_PASSPHRASE }}
will be replaced by the value of the
COUCHDB_PASSPHRASE
environment variable. The template is evaluated at startup
of the stack.
To see the detail of the available parameters available, you can see an example of configuration in the cozy.example.yaml file at the root of this repository.
This file contains all the parameters and fields that can be used to configure the stack with some example values.
Some fields can be overriden by the flags of the cozy-stack serve command.
By default, cozy-stack
use plain-text & local socket for client
(localhost:8080
) and admin (localhost:6060
) communications.
If you want to control a remote stack or using TLS to secure communications, you
can configure your cozy-stack
client with the following CLI arguments or
environment variables.
Argument | Env variable | Default value | Usage |
---|---|---|---|
--host / --admin-host |
COZY_HOST / COZY_ADMIN_HOST |
localhost | [http[s]:https://]<fqdn>[:<port>] |
--port / --admin-port |
COZY_PORT / COZY_ADMIN_PORT |
8080 / 6060 | |
COZY_HOST_TIMEOUT / COZY_ADMIN_TIMOUT |
15s | HTTP timeout to use Must be a valid golang duration like 10s or 1m |
|
COZY_HOST_VALIDATE / COZY_ADMIN_VALIDATE |
true | Enable HTTPS certificate validation Can also be set via host URL query part, like https://localhost:6060?validate=false |
|
COZY_HOST_CA / COZY_ADMIN_CA |
none | CA file to use for HTTPS certificate validation Can also be set via host URL query part, like https://localhost:6060?ca=<ca> |
|
COZY_HOST_CERT / COZY_ADMIN_CERT |
none | Client certificate to use Can also be set via host URL query part, like https://localhost:6060?cert=<cert> |
|
COZY_HOST_KEY / COZY_ADMIN_KEY |
none | Client certificate to use Can also be set via host URL query part, like https://localhost:6060?key=<key> |
|
COZY_HOST_FINGERPRINT / COZY_ADMIN_FINGERPRINT |
none | Hex-encoded SHA-256 key pinning to use Can also be set via host URL query part, like https://localhost:6060?fp=<fp> You can get the fingerprint of a given certificate with openssl x509 -in <certificat.crt> -pubkey | openssl pkey -pubin -outform der | openssl dgst -sha256 -hex or directly from a private key with openssl pkey -in <key.pem> -pubout -outform der | openssl dgst -sha256 -hex |
To access to the administration API (the /admin/*
routes), a secret passphrase
should be stored in a cozy-admin-passphrase
. This file should be in one of the
configuration directories, along with the main config file.
The passphrase is stored in a salted-hashed representation using scrypt. To
generate this file, you can use the cozy-stack config passwd [filepath]
command. This command will ask you for a passphrase and will create the
cozy-admin-passphrase
at the specified path.
You can use the COZY_ADMIN_PASSPHRASE
(or COZY_ADMIN_PASSWORD
) env variable
if you do not want to type the passphrase each time you call cozy-stack
.
$ mkdir ~/.cozy && cozy-stack config passwd ~/.cozy/cozy-admin-passphrase
Hashed passphrase will be writtent in ~/.cozy/cozy-admin-passphrase
Passphrase:
Confirmation:
$ cat ~/.cozy/cozy-admin-passphrase
scrypt$16384$8$1$936bd62faf633b5f946f653c21161a9b$4e0d11dfa5fc1676ed329938b11a6584d30e603e0d06b8a63a99e8cec392d682
The stack can use some temporary directories and files (execution of Image
Magick, konnectors and services for example). And they can take several GB for
the case of importing a Cozy. If needed, it is possible to configure the
directory where they will be created via the TMPDIR
environment variable.
With a large number of instances, a single CouchDB cluster may not be enough. Most cozy-stack administrators can ignore this section, but if you need this advanced settings, let's see how to configure it. We start with a classical configuration for a single cluster:
couchdb:
url: https://cluster1:5984/
The first step is to add the new cluster, but still forces the creation on the first cluster for the moment:
couchdb:
url: https://cluster1:5984/
clusters:
- url: https://cluster1:5984/
instance_creation: true
- url: https://cluster2:5984/
instance_creation: false
Then, we can restart the cozy-stack and everything will work the same, except that the stack now knows how to use an instance on the new cluster. We can now use the second cluster for instance creations instead of the first:
couchdb:
url: https://cluster1:5984/
clusters:
- url: https://cluster1:5984/
instance_creation: false
- url: https://cluster2:5984/
instance_creation: true
Notes:
-
if several CouchDB clusters are configured to accept creations, a new instance will be put in a CouchDB cluster taken randomly
-
each instance document will keep the list index of the CouchDB cluster used for its databases, so don't remove a cluster in the middle of the list!
An integration between Cozy and OnlyOffice has been made. It allows the collaborative edition of office documents in the browser. There are some pre-requistes. OnlyOffice Docs must be installed on a server (The community edition is free but limited to 20 connections and doesn't have the mobile mode). It can be the same server as the stack, but it is tricky as the default port of the stack and of the spellchecker of OnlyOffice is 8080 for both. The stack and the OnlyOffice components must be able to make HTTP requests to each other. And, for security, these requests can be signed via some shared secrets, called inbox and outbox secrets in OnlyOffice configuration.
In the local.json
configuration file of OnlyOffice, we need:
services.CoAuthoring.token.enable.browser
:true
services.CoAuthoring.token.enable.request.inbox
:true
services.CoAuthoring.token.enable.request.outbox
:true
services.CoAuthoring.secret.inbox
: a random secretservices.CoAuthoring.secret.outbox
: another random secret
In the cozy configuration file, we need to add a section with:
office:
default:
onlyoffice_url: https://onlyoffice.example.net/
onlyoffice_inbox_secret: inbox_secret
onlyoffice_outbox_secret: outbox_secret
Don't forget to restart all the services after having made the changes to the configuration files. And you should be able to edit office documents in your browser via the Drive application.
In the config file of cozy-stack, it's possible to declare some contexts, that
are a way to regroup some cozy instances to give similar configuration. For
example, it is possible to give a default_redirection
that will be used
when the user logs into their cozy. You can find more example in the example
config file.
The visual appearance of a cozy instance can be customized via some assets
(CSS, JS, images). These assets can be inserted from the command-line with the
cozy-stack assets add
command.
Here are a small list of assets that you may want to customize:
/styles/theme.css
: a CSS file where you can override the colors and put other CSS rules/favicon.ico
: the old-school favicon/icon.svg
: the favicon in SVG format/icon-192.png
and/icon-512.png
: the two variants of the favicon/apple-touch-icon.png
: the same but for Apple/images/default-avatar.png
: the image to use as the default avatar./images/default-wallpaper.jpg
: the image to use as the default wallpapper on the home./images/icon-cozy-home.svg
: the home icon used and displayed by the cozy-bar./images/icon-cozy-home-inverted.svg
: the home icon used and displayed by the cozy-bar when using the theme inverted.
