Zoe configuration¶
Zoe can be configured by files, environment variables or commandline options. Most of the configuration directives listed in this file can be specified by any of the three methods, with some exception outlined below. Use the --help
command-line option to have more details on the format of environment variables and precedence rules.
Command-line options¶
These options can be specified only on the command-line:
--write-config <filename>
: generate a configuration file with all options set to the default values--log-file <filename>
: write the log output to the specified file instead ofstderr
zoe.conf¶
The Zoe config file have a simple format of <option name> = <value>
. Dash characters can be use for comments.
All Zoe processes use one single configuration file, called zoe.conf. It is searched in the current working directory and in /etc/zoe/
.
Common options:
debug = <true|false>
: enable or disable debug log outputdeployment-name = devel
: name of this Zoe deployment. Can be used to have multiple Zoe deployments using the same back-end (devel and prod, for example)
Workspaces:
workspace-deployment-path
: path appended to theworkspace-base-path
to distinguish this deployment. If left unspecified it is equal to the deployment nameworkspace-base-path = /mnt/zoe-workspaces
: Base directory where user workspaces will be created. This directory should reside on a shared filesystem visible by all hosts where containers will be run.
Metrics:
influxdb-dbname = zoe
: Name of the InfluxDB database to use for storing metricsinfluxdb-url = http://localhost:8086
: URL of the InfluxDB service (ex. )influxdb-enable = False
: Enable metric output toward influxDB
Service logs (see: Zoe logs and service output):
gelf-address
: Enable Docker GELF log output to a UDP listener (ex. udp://1.2.3.4:7896), works only for the Swarm back-endgelf-listener = 7896
: Enable the internal GELF log listener on this port, set to 0 to disableservice-logs-base-path = /var/lib/zoe/service-logs
: Path where service logs coming from the GELF listener will be stored
PostgresQL database options:
dbname = zoe
: DB namedbuser = zoe
: DB userdbpass = zoe
: DB passworddbhost = localhost
: DB hostnamedbport = 5432
: DB port
API options:
listen-address
: address Zoe will use to listen for incoming connections to the web interfacelisten-port
: port Zoe will use to listen for incoming connections to the web interfacemaster-url = tcp://127.0.0.1:4850
: address of the Zoe Master ZeroMQ APIcookie-secret = changeme
: secret used to encrypt cookieszapp-shop-path = /var/lib/zoe-apps
: path to the directory containing the ZApp Shop files
Master options:
api-listen-uri = tcp://*:4850
: ZeroMQ server connection string, used for the master listening endpointkairosdb-enable = false
: Enable gathering of usage metrics recorded in KairosDBkairosdb-url = http://localhost:8090
: URL of KairosDB REST APIoverlay-network-name = zoe
: name of the pre-configured Docker overlay network Zoe should use (Swarm backend)max-core-limit = 16
: maximum amount of cores a user is able to reservemax-memory-limit = 64
: maximum amount of memory a user is able to reserveno-user-edit-limits-web = False
: if set to true, users are NOT allowed to modify ZApp reservations via the web interfaceadditional-volumes = <none>
: list of additional volumes to mount in every service, for every ZApp (ex. /mnt/data:data,/mnt/data_n:data_n)
Authentication:
auth-type = text
: Authentication type (text, ldap or ldapsasl)auth-file = zoepass.csv
: Path to the CSV file containing user,pass,role lines for text authenticationldap-server-uri = ldap://localhost
: LDAP server to use for user authenticationldap-bind-user = ou=something,dc=any,dc=local
: LDAP user for binding to the serverldap-bind-password = mysecretpassword
: Password for the bind userldap-base-dn = ou=something,dc=any,dc=local
: LDAP base DN for usersldap-admin-gid = 5000
: LDAP group ID for adminsldap-user-gid = 5001
: LDAP group ID for usersldap-guest-gid = 5002
: LDAP group ID for guestsldap-group-name = gidNumber
: LDAP user attribute that contains the group names/IDs
Scheduler options:
scheduler-class = <ZoeSimpleScheduler | ZoeElasticScheduler>
: Scheduler class to use for scheduling ZApps (default: elastic scheduler)scheduler-policy = <FIFO | SIZE>
: Scheduler policy to use for scheduling ZApps (default: FIFO)
Default options for the scheduler enable the traditional Zoe scheduler that was already available in the previous releases.
ZApp shop:
zapp-shop-path = /var/lib/zoe-apps
: Path where ZApp folders are stored
Back-end choice:
backend = <DockerEngine|Swarm|Kubernetes>
: cluster back-end to use to run ZApps, default is DockerEngine
Swarm back-end options:
backend-swarm-url = zk://zk1:2181,zk2:2181,zk3:2181
: connection string to the Swarm API endpoint. Can be expressed by a plain http URL or as a zookeeper node list in case Swarm is configured for HA.backend-swarm-zk-path = /docker
: ZooKeeper path used by Docker Swarmbackend-swarm-tls-cert = cert.pem
: Docker TLS certificate filebackend-swarm-tls-key = key.pem
: Docker TLS private key filebackend-swarm-tls-ca = ca.pem
: Docker TLS CA certificate file
Kubernetes back-end:
kube-config-file = /opt/zoe/kube.conf
: the configuration file of Kubernetes cluster that zoe works with. Specified ifbackend
isKubernetes
.
DockerEngine back-end:
backend-docker-config-file = docker.conf
: name of the DockerEngine back-end configuration file
Proxy options:
By default proxy support is disabled. To configure it refer to the proxy documentation.
