I can’t load the Applications screen
After installing Spinnaker and navigating to the Applications screen, you may see one of following issues:
- The following error message is displayed:
Error fetching applications. Check that your gate endpoint is accessible. Further information on troubleshooting this error is available here
The most common cause of this error is that your browser can’t communicate with your Gate endpoint.
(This endpoint defaults to
http://localhost:8084, but can be customized.)
Check your browser console log and/or network for any failed requests to
Some things to check while troubleshooting:
- If you are accessing Spinnaker via the default
http://localhost:9000, check that you have forwarded Gate’s port (8084 by default) to the machine where your browser is running.
- If you are accessing Spinnaker via a custom URL, ensure that you have set
override-base-urlfor both the UI (Deck) and API (Gate) services, as described in the question below . These settings will configure cross-origin resource sharing (CORS) between your Gate and Deck endpoints; if this is not properly configured, your browser will reject requests from Deck to Gate.
- If you have a local deployment of Spinnaker, ensure that Redis is available at the configured address (localhost:6379 by default). If not, start redis by running
sudo systemctl enable redis-server && sudo systemctl start redis-serverand restart spinnaker by running
sudo systemctl restart spinnaker.
I want to expose LocalDebian Spinnaker on a public IP address, but it always binds to localhost
First off, on a local deployment Spinnaker binds to
Your Spinnaker instance has the ability to deploy and destroy a lot of
infrastructure in whatever accounts it manages, and opening it to the public is
not a good idea without authentication enabled. With that in mind, there are
Once you enable an authentication mechanism, Spinnaker will bind the UI and API servers to
0.0.0.0automatically. This is configurable if you prefer to bind a specify address instead. Regardless, you still need to set the API & UI baseUrls so CORS and login redirects happen correctly, this is done with the commands
hal config security ui edit --override-base-url <full ui url>and
hal config security api edit --override-base-url <full api url>.
If you don’t want to rely on authentication, you can follow this guide . This makes sense if you’re running Spinnaker in a private network, or have another form of authentication fronting Spinnaker.
Halyard times out during a config change
Odds are Halyard can’t connect to the configuration & version bucket (in Google
Cloud Storage) it uses to determine if the configuration you’ve provided works
for the version of Spinnaker you want to install. The bucket is
gs://halconfig, see if you can reach it locally using the
The remediation will depend on your local network. You can also always omit
validation with the
As an alternative to
gsutil, you can try querying the bucket directly using its
Halyard times out during a deployment
If this happens, there are one of two causes:
- The services that haven’t become healthy are misconfigured. Run
hal deploy collect-logsto collect service logs, which will be placed in
~/.hal/default/service-logs. Check for any obvious errors.
- You do not have enough resources in your environment to run Spinnaker, and the deployer is waiting for some to become available. This varies from environment to environment.
I want to configure a service beyond what Halyard exposes
First, please read the
documentation. With that in mind, if you’re configuring any of Spinnaker’s
services (everything but deck), you’re
best off providing a
-local.yml profile for the service in mind. For example,
say you are configuring the Halyard
default, and the service
gate, you can write the following file:
and the properties generated by Halyard will be overwritten by those provided
If the service you want to configure does not rely on Spring, you will need to
wholesale overwrite the config in the
I don’t want to rely on any of the configuration generated by Halyard
You have two options here:
- Provide custom configuration for any services whose config you prefer to override.
- Deploy Spinnaker with the
--omit-configflag. In the Local installation, this will pin & download validated debian packages at their respective versions without providing any configuration. In a Distributed installation, you will need to provide your own mechanisms for loading configuration for each subservice.
I’m seeing duplicate/bad infrastructure entries in the UI after deploying config changes
Spinnaker’s cloud provider integration point (clouddriver) does not clean out
cache entries that may be left around after reconfiguring existing
accounts. The best way to get around this is to supply the
--flush-infrastructure-caches to a
hal deploy apply. This may cause
jittering in the UI as the caches are repopulated.
I want to decouple my Halyard configuration from a single machine
Please read the backup documentation .
Halyard produces a lot of ugly ANSI escape sequences making it frustrating to automate
You can supply the flags
-q -log=info to any Halyard command to get more
digestable log messages.
-q suppresses the ANSI pretty-printing, and
-log=info enables info-level logs in the CLI.
I don’t want to use a bunch of CLI commands to configure Spinnaker; I prefer my text editor
Anything in the
~/.hal/config can be edited by hand at any time. You can
validate what you provide there by running
hal config, and deploy it as you
hal deploy apply. For more service-specific edits, please read
I only want to deploy a subset of Spinnaker’s services
You can run
hal deploy apply --service-names <service1> <service2...> to
deploy only the services you care about. Be careful, if you have sidecars like
monitoring-daemon or the
consul-client for a VM based distributed
deployment, you will have to supply those as well.
This can be coupled with
--omit-config in a local installation to provide a
taylored way of deploying & configuring only the services you want on the
machines you care about.
I want to run Halyard behind a proxy
In the file under
/opt/halyard/bin/halyard, add the necessary proxy
configuration to the variable
DEFAULT_JVM_OPTS as described
I want to run a Spinnaker service (Clouddriver, Echo, etc) behind an HTTP proxy server
For most Spinnaker service communication, this can be accomplished by setting appropriate
JVM options for the service you want to proxy. For example, if you wanted to proxy Echo
communication for Slack notifications, you would add the following proxy settings to
"-XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap -XX:MaxRAMFraction=2
-Dhttp.proxyHost=<proxy host> -Dhttp.proxyPort=<proxy port> -Dhttps.proxyHost=<proxy host>
-Dhttps.proxyPort=<proxy port> -Dhttp.nonProxyHosts='localhost|127.*|[::1]|*.spinnaker'"
These settings will forward all external communication through the proxy server specified while keeping internal traffic non-proxied. Additional information can be found here.
The Kubernetes provider must be handled differently. Because the Kubernetes provider
kubectl (which uses curl), you must set environment variables if you want
Kubernetes traffic to be proxied.
clouddriver.yml that will proxy Kubernetes traffic will look like:
What is the best way to delete a Spinnaker deployment?
hal deploy clean to delete an existing Spinnaker deployment. Note that this command destroys all Spinnaker artifacts in your target deployment environment. So, use it with caution and back up your configuration in case you want to restore it.
After Spinnaker is deleted, delete Halyard by running
