Using multiple configs is great for deploying to different environments but having multiple configs makes it a lot harder to keep everything consistent and up-to-date across different configurations.
To reduce the effort of maintaining many different configuration files with similar contents, DevSpace allows you to define config overrides for your configs. This allows yo to:
- Create one config file (base config)
- Define multiple configs in
.devspace/configs.yamlwhich all load the same config file (using the
pathoption for each config)
- Define config overrides for the different configs in
Defining configs with overrides
config1: config: path: ../devspace.yaml config2: config: path: ../devspace.yaml overrides: - data: images: database: image: dscr.io/my-username/alternative-db-image
The above example defines two configurations
config2. Both will load the same config file
config2 is slightly different because it will apply an override after loading the config file. This override defines that
images.database.image should be overriden with the value
Advanced options for config overrides
Instead of specifying overrides directly inside
data, it is also possible to define a file containing the override data and reference this file with
path instead of using
As shown in the example above,
overrides is an array which allows you to apply multiple overrides. This can be useful when you want to re-use an override file multiple times but also apply additional overrides which are different between several configs.
Is it possible to override a single entry within an array? (e.g. overriding single deployments)
No. It is, for example, not possible to override one specific deployment defined in the
deployments section of a config file. Overriding the
deployments would always override the entire array of
How is config overriding different from entrypoint overriding?
Entrypoint overriding is a convenience feature that is specifically designed for
devspace dev and will only be applied when running
Config overriding is an advanced feature that allows you to override parts of a configuration. Config overrides impact any command you run, i.e.
devspace dev AND
devspace deploy as well as for any other command that you run using this overridden config.
