tsuru.conf reference¶
tsuru uses a configuration file in YAML format. This document describes what each option means, and how it should look.
Notation¶
tsuru uses a colon to represent nesting in YAML. So, whenever this document says
something like key1:key2
, it refers to the value of the key2
that is
nested in the block that is the value of key1
. For example,
database:url
means:
database:
url: <value>
tsuru configuration¶
This section describes tsuru’s core configuration. Other sections will include configuration of optional components, and finally, a full sample file.
HTTP server¶
tsuru provides a REST API, that supports HTTP and HTTP/TLS (a.k.a. HTTPS). Here are the options that affect how tsuru’s API behaves:
listen¶
listen
defines in which address tsuru webserver will listen. It has the
form <host>:<port>. You may omit the host (example: :8080
). This setting
has no default value.
shutdown-timeout¶
shutdown-timeout
defines how many seconds to wait when performing an api
shutdown (by sending SIGTERM or SIGQUIT). Defaults to 600 seconds.
use-tls¶
use-tls
indicates whether tsuru should use TLS or not. This setting is
optional, and defaults to “false”.
tls:listen¶
If both this and listen
keys are set (following the same rules as listen
key), tsuru will start two webserver instances: one with HTTP on listen
address, and the other one with HTTPS on tls:listen
address.
If only one of listen
and tls:listen
keys is set (and use-tls
is
true), tsuru will only run the TLS supporting webserver. This setting is
optional, unless use-tls
is true.
tls:cert-file¶
tls:cert-file
is the path to the X.509 certificate file configured to serve
the domain. This setting is optional, unless use-tls
is true.
tls:key-file¶
tls:key-file
is the path to private key file configured to serve the
domain. This setting is optional, unless use-tls
is true.
tls:validate-certificate¶
tls:validate-certificate
prevents an invalid certificate from being offered
to web clients or not. This setting is optional and defaults to “false”.
If enabled, the server will validate the certificates before server’s start and during the certificates auto-reload process (if any). If a certificate expires during server execution (after loaded by server) this feature will gracefully shutdown the server.
tls:auto-reload:interval¶
tls:auto-reload:interval
defines the time frequency which the TLS
certificates are reloaded by the webserver. A new certificate only is loaded
when there is difference between newer and older.
This setting is optional. The default value is 0, which means automatic reload is not enabled. To enable it, you could use any time.Duration value greater than zero, as well as parseable values as: “1h”, “60m”, “3600s”, etc.
server:read-timeout¶
server:read-timeout
is the timeout of reading requests in the server. This
is the maximum duration of any request to the tsuru server.
This is useful to avoid leaking connections, in case clients drop the connection before end sending the request. The default value is 0, meaning no timeout.
server:write-timeout¶
server:write-timeout
is the timeout of writing responses in the server.
This is useful to avoid leaking connections, in case clients drop the connection before reading the response from tsuru. The default value is 0, meaning no timeout.
server:app-log-buffer-size¶
The maximum number of received log messages from applications to hold in memory waiting to be sent to the log database. The default value is 500000.
disable-index-page¶
tsuru API serves an index page with some basic instructions on how to use the
current target. It’s possible to disable this page by setting the
disable-index-page
flag to true. It’s also possible to customize which
template will be used in the index page, see the next configuration entry for
more details.
This setting is optional, and defaults to false
.
index-page-template¶
index-page-template
is the template that will be used for the index page.
It must use the Go template syntax,
and tsuru will provide the following variables in the context of the template:
tsuruTarget
: the target URL of the tsuru API serving the index pageuserCreate
: a boolean indicating whether user registration is enabled or disablednativeLogin
: a boolean indicating whether the API is configured to use the native authentication schemekeysEnabled
: a boolean indicating whether the API is configured to manage SSH keys
It will also include a function used for querying configuration values, named
getConfig
. Here is an example of the function usage:
<body>
{{if getConfig "use-tls"}}
<p>we're safe</p>
{{else}}
<p>we're not safe</p>
{{end}}
</body>
This setting is optional. When index-page-template
is not defined, tsuru
will use the default template.
reset-password-template¶
reset-password-template
is the template that will be used to “password reset” email.
It must use the Go template syntax,
and tsuru will provide the following variables in the context of the template:
Token
: a string, the id of password reset requestUserEmail
: a string, the user emailCreation
: a time, when password reset was requestedUsed
: a boolean, reset-password was done or not
This setting is optional. When reset-password-template
is not defined, tsuru
will use the default template.
reset-password-successfully-template¶
reset-password-successfully-template
is the template that will be used to email with new password, after reset.
It must use the Go template syntax,
and tsuru will provide the following variables in the context of the template:
password
: a string, the new password
This setting is optional. When reset-password-template
is not defined, tsuru
will use the default template.
Database access¶
tsuru uses MongoDB as a database manager to store information like users, machines, containers, etc. You need to describe how tsuru will connect to your database server. Therefore, it’s necessary to provide a MongoDB connection string. Database related options are listed below:
database:url¶
database:url
is the database connection string. It is a mandatory setting
and it has no default value. Examples of strings include basic 127.0.0.1
and
more advanced mongodb://user:password@127.0.0.1:27017/database
. Please refer
to MongoDB documentation for more details
and examples of connection strings.
database:name¶
database:name
is the name of the database that tsuru uses. It is a
mandatory setting and has no default value. An example of value is “tsuru”.
database:driver¶
database:driver
is the name of the database driver that tsuru uses.
Currently, the only value supported is “mongodb”.
Email configuration¶
tsuru sends email to users when they request password recovery. In order to send those emails, tsuru needs to be configured with some SMTP settings. Omitting these settings won’t break tsuru, but users will not be able to reset their password.
smtp:server¶
The SMTP server to connect to. It must be in the form <host>:<port>. Example: “smtp.gmail.com:587”.
smtp:user¶
The user to authenticate with the SMTP sever. Currently, tsuru requires authenticated sessions.
smtp:password¶
The password for authentication within the SMTP server.
Authentication configuration¶
tsuru has support for native
, oauth
and saml
authentication schemes.
The default scheme is native
and it supports the creation of users in
tsuru’s internal database. It hashes passwords brcypt. Tokens are generated
during authentication and are hashed using SHA512.
The auth
section also controls whether user registration is on or off. When
user registration is off, only admin users are able to create new users.
auth:scheme¶
The authentication scheme to be used. The default value is native
, the other
supported value is oauth
.
auth:user-registration¶
This flag indicates whether user registration is enabled. This setting is optional, and defaults to false.
auth:hash-cost¶
Required only with native
chosen as auth:scheme
.
This number indicates how many CPU time you’re willing to give to hashing calculation. It is an absolute number, between 4 and 31, where 4 is faster and less secure, while 31 is very secure and very slow.
auth:token-expire-days¶
Required only with native
chosen as auth:scheme
.
Whenever a user logs in, tsuru generates a token for him/her, and the user may
store the token. auth:token-expire-days
setting defines the amount of days
that the token will be valid. This setting is optional, and defaults to “7”.
auth:max-simultaneous-sessions¶
tsuru can limit the number of simultaneous sessions per user. This setting is optional, and defaults to “unlimited”.
auth:oauth¶
Every config entry inside auth:oauth
are used when the auth:scheme
is
set to “oauth”. Please check rfc6749 for
more details.
auth:oauth:client-id¶
The client id provided by your OAuth server.
auth:oauth:client-secret¶
The client secret provided by your OAuth server.
auth:oauth:scope¶
The scope for your authentication request.
auth:oauth:auth-url¶
The URL used in the authorization step of the OAuth flow. tsuru CLI will receive this URL and trigger the opening a browser on this URL with the necessary parameters.
During the authorization step, tsuru CLI will start a server locally and set the
callback to http://localhost:<port>, if auth:oauth:callback-port
is set
tsuru CLI will use its value as <port>. If auth:oauth:callback-port
isn’t
present tsuru CLI will automatically choose an open port.
The callback URL should be registered on your OAuth server.
If the chosen server requires the callback URL to match the same host and port
as the registered one you should register “http://localhost:<chosen port>” and
set the auth:oauth:callback-port
accordingly.
If the chosen server is more lenient and allows a different port to be used you
should register simply “http://localhost” and leave auth:oauth:callback-port
empty.
auth:oauth:token-url¶
The URL used in the exchange token step of the OAuth flow.
auth:oauth:info-url¶
The URL used to fetch information about the authenticated user. tsuru expects a
json response containing a field called email
.
tsuru will also make call this URL on every request to the API to make sure the token is still valid and hasn’t been revoked.
auth:oauth:collection¶
The database collection used to store valid access tokens. Defaults to “oauth_tokens”.
auth:oauth:callback-port¶
The port used in the callback URL during the authorization step. Check docs for
auth:oauth:auth-url

as storage for delayed execution of queued jobs.
This queue is used to manage creation and destruction of IaaS machines, but tsuru may start using it in more places in the future.
It’s not mandatory to configure the queue, however creating and removing machines using a IaaS provider will not be possible.
queue:mongo-url¶
Connection url for MongoDB server used to store task information.

tsuru can, optionally, manage quotas. Currently, there are two available quotas: apps per user and units per app.
tsuru administrators can control the default quota for new users and new apps
in the configuration file, and use tsuru
command to change quotas for
users or apps. Quota management is disabled by default, to enable it, just set
the desired quota to a positive integer.

The default behavior of tsuru is to send all logs to syslog, but it can also send logs to the standard error stream or a file. It’s is possible to use any combination of the three flavors at any time in tsuru configuration (e.g.: write logs both to stderr and syslog, or a file and stderr, or to all of the flavors simultaneously).
There’s also the possibility to enable or disable debugging log, via the debug flag.
debug¶
false
is the default value, so you won’t see any
noises on logs, to turn it on set it to true, e.g.: debug: true

The amount of memory available is found based on the node metadata described by
docker:scheduler:total-memory-metadata
config setting.
If this value is set, tsuru will try to find a node with enough unreserved memory to fit the creation of new units, based on how much memory is required by the plan used to create the application. If no node with enough unreserved memory is found, tsuru will ignore memory restrictions and let the scheduler choose any node.

for this will make tsuru use the platform image user.
docker:uid¶
The user ID tsuru will use to start the container in provisioners that do not
support docker:user
. The default value is 1000
, which is the expected
value for default tsuru platforms. The value -1

Remote script to be used for docker installation. Defaults to: http://get.docker.com.
iaas:dockermachine:docker-storage-driver¶
Docker engine storage driver
iaas:dockermachine:insecure-registry¶
Registry to be added as insecure registry to the docker engine.
iaas:dockermachine:docker-flags¶
Additional flags to be set on the docker engine.
Custom IaaS¶
You can define a custom IaaS based on an existing provider. Any configuration
keys with the format iaas:custom:<name>
will create a new IaaS with
name
.
iaas:custom:<name>:provider¶
The base provider name, it can be any of the supported providers: cloudstack
,
ec2
, digitalocean
or dockermachine
.
iaas:custom:<name>:<any_other_option>¶
This will overwrite the value of iaas:<provider>:<any_other_option>
for this
IaaS. As an example, having the configuration below would allow you to call
tsuru node-add iaas=region1_cloudstack ...
:
iaas:
custom:
region1_cloudstack:
provider: cloudstack
url: http://region1.url/
secret-key: mysecretkey
cloudstack:
api-key: myapikey
Event throttling configuration¶
event:throttling¶
Event throttling is a list of throttling settings that will match events based on their target and kind. Each list entry has the config options described below.
event:throttling:[]:target-type¶
The target type this throttling config will match. This option is mandatory for every throttling entry.
event:throttling:[]:kind-name¶
The event kind name this throttling config will match. If not set this throttling config will match all events based on ther target-type regardless of the kind name.
event:throttling:[]:limit¶
Positive integer representing maximum number of events in event:throttling:[]:window
time. Use 0 to disable throttling.
event:throttling:[]:window¶
Number of seconds for the rolling window for events in which event:throttling:[]:limit
will be considered.
event:throttling:[]:wait-finish¶
Boolean value describing whether tsuru will only execute a new event after previous ones were completed or not, even if the time window already allows the execution of a new event.
event:throttling:[]:all-targets¶
Boolean value describing whether the throttling will apply to all events target values or to individual values.
Security configuration¶
events:suppress-sensitive-envs¶
Boolean value used to enable suppression of sensitive environment variables on tsuru event-info and tsuru-dashboard.
Defaults to false
, will be true
in next minor version.
Volume plans configuration¶
volume-plans:<plan-name>:<provisioner>¶
Provisioner specific configuration entries for the volume plan. See managing volumes.
Common redis configuration options¶
<prefix>:redis-server¶
Connect to a single redis server. The redis server address should be in the
format host:port
. This parameter is mutually exclusive with
<prefix>:redis-sentinel-addrs
and <prefix>:redis-cluster-addrs
.
<prefix>:redis-host¶
Alternative way to specify a single redis server to connect. Only the host
name should be informed.
<prefix>:redis-port¶
The port used when <prefix>:redis-host
is defined.
<prefix>:redis-sentinel-addrs¶
Connect to a farm of redis sentinel servers. It’s a comma separated list of
host:port
pairs. e.g.: 10.0.0.1:26379,10.0.0.2:26379
. This parameter is
mutually exclusive with <prefix>:redis-server
and
<prefix>:redis-cluster-addrs
.
<prefix>:redis-sentinel-master¶
The master name for a sentinel farm. This parameter is mandatory when
<prefix>:redis-sentinel-addrs
is defined.
<prefix>:redis-cluster-addrs¶
Connect to a farm of redis cluster servers. It’s a comma separated list of
host:port
pairs. e.g.: 10.0.0.1:6379,10.0.0.2:6379
. This parameter is
mutually exclusive with <prefix>:redis-server
and
<prefix>:redis-sentinel-addrs
.
<prefix>:redis-db¶
The db number selected when connecting to redis.
<prefix>:redis-password¶
The password used when connecting to redis.
<prefix>:redis-pool-size¶
The maximum number of simultaneously open connections to a redis server.
<prefix>:redis-max-retries¶
The number of times an unsuccessful command will be sent to redis again.
<prefix>:redis-pool-timeout¶
Duration in seconds to wait for a free redis connection once the maximum pool
size defined in <prefix>:redis-pool-size
is reached.
<prefix>:redis-pool-idle-timeout¶
Duration in seconds after which an idle connection will be discarded from the pool.
<prefix>:redis-dial-timeout¶
Duration in seconds after which an error will be returned if a connection to redis cannot be established.
<prefix>:redis-read-timeout¶
Duration in seconds after which an error will be returned if tsuru is still waiting for the response for an issued command.
<prefix>:redis-write-timeout¶
Duration in seconds after which an error will be returned if tsuru is still sending a command to redis.
