Deploy Kubernetes Manifests
To deploy Kubernetes manifests with kubectl apply, you need to configure them within the deployments section of the devspace.yaml.
Example#
The above example will be executing during the deployment process as follows:
Kubectl
Deployments with kubectl require kubectl to be installed. If the kubectl binary cannot be found within the $PATH variable and it is not specified by specifying the cmdPath option, DevSpace will download the kubectl binary into the $HOME/.devspace/bin folder.
Manifests#
manifests#
The manifests option is mandatory and expects an array of paths or path globs that point to Kubernetes manifest files (yaml or json files) or to folders containing Kubernetes manifests or Kustomizations.
Example: Manifests#
kustomize#
The kustomize option expects a boolean stating if DevSpace should deploy using kustomize (or alternatively: kubectl apply -k).
warning
If you set kustomize = true, all of your manifests must be paths to Kustomizations. If you want to deploy some plain manifests and some Kustomizations, create multiple deployments for each of them.
Default Value for kustomize#
Example: Kustomize#
replaceImageTags#
The replaceImageTags option expects a boolean stating if DevSpace should replace/update all image tags before deploying the project.
By default, DevSpace searches all your manifests for images that are defined in the images section of the devspace.yaml. If DevSpace finds an image, it replaces or appends the image tag with the tag it created during the image building process. Image tag replacement makes sure that your application will always be started with the most up-to-date image that DevSpace has built for you.
In-Memory Tag Replacement
Tag replacement takes place in-memory and is not writing anything to the filesystem, i.e. it will never change any of your configuration files.
Default Value for replaceImageTags#
Example: Disable Tag Replacement#
Kubectl Options#
applyArgs#
The applyArgs option expects an array of strings stating additional arguments (and flags) that should be used when calling kubectl apply.
Apply for Kustomize Deployments
Even if you set kustomize: true, DevSpace only renders the manifest templates using kustomize but the actual deployment will be executed using kubectl apply.
Default Value for applyArgs#
Example: Custom Kubectl Args & Flags#
Explanation:
Deploying the above example would roughly be equivalent to this command:
createArgs#
The createArgs option expects an array of strings stating additional arguments (and flags) that should be used when calling kubectl create.
Kustomize Deployments
DevSpace only uses kustomize create to render the manifests using the default flags --dry-run --output yaml --validate=false. The actual deployment will be executed using kubectl apply after DevSpace has replaced the image tags within the rendered manifests in memory.
Default Value for createArgs#
Example: Custom Kubectl Args & Flags#
Explanation: Deploying the above example would roughly be equivalent to this command:
deleteArgs#
The deleteArgs option expects an array of strings stating additional arguments (and flags) that should be used when calling kubectl delete.
Purging Deployments
For plain manifests or Kustomizations, DevSpace uses kubectl delete to remote deployments when you run the command devspace purge.
Default Value for deleteArgs#
Example: Custom Kubectl Args & Flags#
Explanation:
Deploying the above example would roughly be equivalent to this command:
cmdPath#
The cmdPath option expects an array of strings stating additional flags and flag values that should be used when calling kubectl apply.
warning
Setting cmdPath makes it much harder to share your devspace.yaml with other team mates. It is recommended to add kubectl to your $PATH environment variable instead.
Example: Setting Path To Kubectl Binary#
Explanation:
Deploying the above example would roughly be equivalent to this command:
General Options#
name#
The name option is required and expects a string to identify this deployment.
Example: Deployment Name#
namespace#
The namespace option is required and expects a string with the namespace used to deploy the manifests.
warning
Only use this option if you really need to. Hard-coding the namespace in devspace.yaml makes it harder to share the configuration with your colleagues. It is recommended to set the default namespace of the current context instead using:
