Buckets

The Bucket API defines a Source to produce an Artifact for objects from storage solutions like Amazon S3, Google Cloud Storage buckets, or any other solution with a S3 compatible API such as Minio, Alibaba Cloud OSS and others.

Example

The following is an example of a Bucket. It creates a tarball (.tar.gz) Artifact with the fetched objects from an object storage with an S3 compatible API (e.g. Minio):

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: minio-bucket
  namespace: default
spec:
  interval: 5m0s
  endpoint: minio.example.com
  insecure: true
  secretRef:
    name: minio-bucket-secret
  bucketName: example
---
apiVersion: v1
kind: Secret
metadata:
  name: minio-bucket-secret
  namespace: default
type: Opaque
stringData:
  accesskey: <access key>
  secretkey: <secret key>

In the above example:

A Bucket named minio-bucket is created, indicated by the .metadata.name field.
The source-controller checks the object storage bucket every five minutes, indicated by the .spec.interval field.
It authenticates to the minio.example.com endpoint with the static credentials from the minio-secret Secret data, indicated by the .spec.endpoint and .spec.secretRef.name fields.
A list of object keys and their etags in the .spec.bucketName bucket is compiled, while filtering the keys using default ignore rules.
The SHA256 sum of the list is used as Artifact revision, reported in-cluster in the .status.artifact.revision field.
When the current Bucket revision differs from the latest calculated revision, all objects are fetched and archived.
The new Artifact is reported in the .status.artifact field.

You can run this example by saving the manifest into bucket.yaml, and changing the Bucket and Secret values to target a Minio instance you have control over.

Note: For more advanced examples targeting e.g. Amazon S3 or GCP, see Provider.

Apply the resource on the cluster:
```
kubectl apply -f bucket.yaml
```

Run kubectl get buckets to see the Bucket:

Writing a Bucket spec

As with all other Kubernetes config, a Bucket needs apiVersion, kind, and metadata fields. The name of a Bucket object must be a valid DNS subdomain name.

A Bucket also needs a .spec section.

Provider

The .spec.provider field allows for specifying a Provider to enable provider specific configurations, for example to communicate with a non-S3 compatible API endpoint, or to change the authentication method.

Supported options are:

Generic
AWS
Azure
GCP

If you do not specify .spec.provider, it defaults to generic.

Generic

When a Bucket's spec.provider is set to generic, the controller will attempt to communicate with the specified Endpoint using the Minio Client SDK, which can communicate with any Amazon S3 compatible object storage (including GCS, Wasabi, and many others).

The generic Provider requires a Secret reference to a Secret with .data.accesskey and .data.secretkey values, used to authenticate with static credentials.

The Provider allows for specifying a region the bucket is in using the .spec.region field, if required by the Endpoint.

Generic example

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: generic-insecure
  namespace: default
spec:
  provider: generic
  interval: 5m0s
  bucketName: podinfo
  endpoint: minio.minio.svc.cluster.local:9000
  timeout: 60s
  insecure: true
  secretRef:
    name: minio-credentials
---
apiVersion: v1
kind: Secret
metadata:
  name: minio-credentials
  namespace: default
type: Opaque
data:
  accesskey: <BASE64>
  secretkey: <BASE64>

AWS

When a Bucket's .spec.provider field is set to aws, the source-controller will attempt to communicate with the specified Endpoint using the Minio Client SDK.

Without a Secret reference, authorization using credentials retrieved from the AWS EC2 service is attempted by default. When a reference is specified, it expects a Secret with .data.accesskey and .data.secretkey values, used to authenticate with static credentials.

The Provider allows for specifying the Amazon AWS Region using the .spec.region field.

AWS EC2 example

Note: On EKS you have to create an IAM role for the source-controller service account that grants access to the bucket.

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: aws
  namespace: default
spec:
  interval: 5m0s
  provider: aws
  bucketName: podinfo
  endpoint: s3.amazonaws.com
  region: us-east-1
  timeout: 30s

AWS IAM role example

Replace <bucket-name> with the specified .spec.bucketName.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
            "Effect": "Allow",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::<bucket-name>/*"
        },
        {
            "Sid": "",
            "Effect": "Allow",
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::<bucket-name>"
        }
    ]
}

AWS static auth example

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: aws
  namespace: default
spec:
  interval: 5m0s
  provider: aws
  bucketName: podinfo
  endpoint: s3.amazonaws.com
  region: us-east-1
  secretRef:
    name: aws-credentials
---
apiVersion: v1
kind: Secret
metadata:
  name: aws-credentials
  namespace: default
type: Opaque
data:
  accesskey: <BASE64>
  secretkey: <BASE64>

Azure

When a Bucket's .spec.provider is set to azure, the source-controller will attempt to communicate with the specified Endpoint using the Azure Blob Storage SDK for Go.

Without a Secret reference, authentication using a chain with:

Environment credentials
Managed Identity with the AZURE_CLIENT_ID
Managed Identity with a system-assigned identity

is attempted by default. If no chain can be established, the bucket is assumed to be publicly reachable.

When a reference is specified, it expects a Secret with one of the following sets of .data fields:

tenantId, clientId and clientSecret for authenticating a Service Principal with a secret.
tenantId, clientId and clientCertificate (plus optionally clientCertificatePassword and/or clientCertificateSendChain) for authenticating a Service Principal with a certificate.
clientId for authenticating using a Managed Identity.
accountKey for authenticating using a Shared Key.

For any Managed Identity and/or Azure Active Directory authentication method, the base URL can be configured using .data.authorityHost. If not supplied, AzurePublicCloud is assumed.

Azure example

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket

---
apiVersion: v1
kind: Secret
metadata:
  name: azure-key
  namespace: default
type: Opaque
data:
  accountKey: <BASE64>

GCP

When a Bucket's .spec.provider is set to gcp, the source-controller will attempt to communicate with the specified Endpoint using the Google Client SDK.

Without a Secret reference, authorization using a workload identity is attempted by default. The workload identity is obtained using the GOOGLE_APPLICATION_CREDENTIALS environment variable, falling back to the Google Application Credential file in the config directory. When a reference is specified, it expects a Secret with a .data.serviceaccount value with a GCP service account JSON file.

The Provider allows for specifying the Bucket location using the .spec.region field.

GCP example

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: gcp-workload-identity
  namespace: default
spec:
  interval: 5m0s
  provider: gcp
  bucketName: podinfo
  endpoint: storage.googleapis.com
  region: us-east-1
  timeout: 30s

GCP static auth example

---
apiVersion: source.toolkit.fluxcd.io/v1beta2

}

Interval

.spec.interval is a required field that specifices the interval which the object storage bucket must be consulted at.

After successfully reconciling a Bucket object, the source-controller requeues the object for inspection after the specified interval. The value must be in a Go recognized duration string format, e.g. 10m0s to look at the object storage bucket every 10 minutes.

If the .metadata.generation of a resource changes (due to e.g. the apply of a change to the spec), this is handled instantly outside of the interval window.

Endpoint

.spec.endpoint is a required field that specifies the HTTP/S object storage endpoint to connect to and fetch objects from. Connecting to an (insecure) HTTP endpoint requires enabling .spec.insecure.

Some endpoints require the specification of a .spec.region, see Provider for more (provider specific) examples.

Bucket name

.spec.bucketName is a required field that specifies which object storage bucket on the Endpoint objects should be fetched from.

See Provider for more (provider specific) examples.

Region

.spec.region is an optional field to specify the region a .spec.bucketName is located in.

See Provider for more (provider specific) examples.

Insecure

.spec.insecure is an optional field to allow connecting to an insecure (HTTP) endpoint, if set to true. The default value is false, denying insecure (HTTP) connections.

Timeout

.spec.timeout is an optional field to specify a timeout for object storage fetch operations. The value must be in a Go recognized duration string format, e.g. 1m30s for a timeout of one minute and thirty seconds. The default value is 60s.

Secret reference

.spec.secretRef.name is an optional field to specify a name reference to a Secret in the same namespace as the Bucket, containing authentication credentials for the object storage. For some .spec.provider implementations the presence of the field is required, see Provider for more details and examples.

Ignore

.spec.ignore is an optional field to specify rules in the .gitignore pattern format. Storage objects which keys match the defined rules are excluded while fetching.

When specified, .spec.ignore overrides the default exclusion list, and may overrule the .sourceignore file exclusions. See excluding files for more information.

Suspend

.spec.suspend is an optional field to suspend the reconciliation of a Bucket. When set to true, the controller will stop reconciling the Bucket, and changes to the resource or in the object storage bucket will not result in a new Artifact. When the field is set to false or removed, it will resume.

For practical information, see suspending and resuming.

Working with Buckets

Excluding files

By default, storage bucket objects which match the default exclusion rules are excluded while fetching. It is possible to overwrite and/or overrule the default exclusions using a file in the bucket and/or an in-spec set of rules.

`.sourceignore` file

Excluding files is possible by adding a .sourceignore file in the root of the object storage bucket. The .sourceignore file follows the .gitignore pattern format, and pattern entries may overrule default exclusions.

Ignore spec

Another option is to define the exclusions within the Bucket spec, using the .spec.ignore field. Specified rules override the default exclusion list, and may overrule .sourceignore file exclusions.

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: <bucket-name>
spec:
  ignore: |
    # exclude all
    /*
    # include deploy dir
    !/deploy
    # exclude file extensions from deploy dir
    /deploy/**/*.md
    /deploy/**/*.txt

Triggering a reconcile

To manually tell the source-controller to reconcile a Bucket outside of the specified interval window, a Bucket can be annotated with reconcile.fluxcd.io/requestedAt: <arbitrary value>. Annotating the resource queues the Bucket for reconciliation if the <arbitrary-value> differs from the last value the controller acted on, as reported in .status.lastHandledReconcileAt.

Using kubectl:

kubectl annotate --field-manager=flux-client-side-apply --overwrite  bucket/<bucket-name> reconcile.fluxcd.io/requestedAt="$(date +%s)"

Using flux:

flux reconcile source bucket <bucket-name>

Waiting for `Ready`

When a change is applied, it is possible to wait for the Bucket to reach a ready state using kubectl:

kubectl wait bucket/<bucket-name> --for=condition=ready --timeout=1m

Suspending and resuming

When you find yourself in a situation where you temporarily want to pause the reconciliation of a Bucket, you can suspend it using the .spec.suspend field.

Suspend a Bucket

In your YAML declaration:

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: <bucket-name>
spec:
  suspend: true

Using kubectl:

kubectl patch bucket <bucket-name> --field-manager=flux-client-side-apply -p '{\"spec\": {\"suspend\" : true }}'

Using flux:

flux suspend source bucket <bucket-name>

Note: When a Bucket has an Artifact and is suspended, and this Artifact later disappears from the storage due to e.g. the source-controller Pod being evicted from a Node, this will not be reflected in the Bucket's Status until it is resumed.

Resume a Bucket

In your YAML declaration, comment out (or remove) the field:

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: Bucket
metadata:
  name: <bucket-name>
spec:
  # suspend: true

Note: Setting the field value to false has the same effect as removing it, but does not allow for "hot patching" using e.g. kubectl while practicing GitOps; as the manually applied patch would be overwritten by the declared state in Git.

Using kubectl:

kubectl patch bucket <bucket-name> --field-manager=flux-client-side-apply -p '{\"spec\" : {\"suspend\" : false }}'

Using flux:

flux resume source bucket <bucket-name>

Debugging a Bucket

There are several ways to gather information about a Bucket for debugging purposes.

Describe the Bucket

Describing a Bucket using kubectl describe bucket <bucket-name> displays the latest recorded information for the resource in the Status and Events sections:

...

Trace emitted Events

To view events for specific Bucket(s), kubectl get events can be used in combination with --field-sector to list the Events for specific objects. For example, running

kubectl get events --field-selector involvedObject.kind=Bucket,involvedObject.name=<bucket-name>

lists

LAST SEEN   TYPE      REASON                       OBJECT                 MESSAGE

Besides being reported in Events, the reconciliation errors are also logged by the controller. The Flux CLI offer commands for filtering the logs for a specific Bucket, e.g. flux logs --level=error --kind=Bucket --name=<bucket-name>.

Bucket Status

Artifact

The Bucket reports the latest synchronized state from the object storage bucket as an Artifact object in the .status.artifact of the resource.

The Artifact file is a gzip compressed TAR archive (<calculated revision>.tar.gz), and can be retrieved in-cluster from the .status.artifact.url HTTP address.

Artifact example

Default exclusions

The following files and extensions are excluded from the Artifact by default:

Git files (.git/, .gitignore, .gitmodules, .gitattributes)
File extensions (.jpg, .jpeg, .gif, .png, .wmv, .flv, .tar.gz, .zip)
CI configs (.github/, .circleci/, .travis.yml, .gitlab-ci.yml, appveyor.yml, .drone.yml, cloudbuild.yaml, codeship-services.yml, codeship-steps.yml)
CLI configs (.goreleaser.yml, .sops.yaml)
Flux v1 config (.flux.yaml)

To define your own exclusion rules, see excluding files.

Conditions

A Bucket enters various states during its lifecycle, reflected as Kubernetes Conditions. It can be reconciling while fetching storage objects, it can be ready, or it can fail during reconciliation.

The Bucket API is compatible with the kstatus specification, and reports Reconciling and Stalled conditions where applicable to provide better (timeout) support to solutions polling the Bucket to become Ready.

Reconciling Bucket

The source-controller marks a Bucket as reconciling when one of the following is true:

There is no current Artifact for the Bucket, or the reported Artifact is determined to have disappeared from the storage.
The generation of the Bucket is newer than the Observed Generation.
The newly calculated Artifact revision differs from the current Artifact.

When the Bucket is "reconciling", the Ready Condition status becomes False, and the controller adds a Condition with the following attributes to the Bucket's .status.conditions:

type: Reconciling
status: "True"
reason: NewGeneration | reason: NoArtifact | reason: NewRevision

If the reconciling state is due to a new revision, an additional Condition is added with the following attributes:

type: ArtifactOutdated
status: "True"
reason: NewRevision

Both Conditions have a "negative polarity", and are only present on the Bucket while their status value is "True".

Ready Bucket

The source-controller marks a Bucket as ready when it has the following characteristics:

The Bucket reports an Artifact.
The reported Artifact exists in the controller's Artifact storage.
The Bucket was able to communicate with the Bucket's object storage endpoint using the current spec.
The revision of the reported Artifact is up-to-date with the latest calculated revision of the object storage bucket.

When the Bucket is "ready", the controller sets a Condition with the following attributes in the Bucket's .status.conditions:

type: Ready
status: "True"
reason: Succeeded

This Ready Condition will retain a status value of "True" until the Bucket is marked as reconciling, or e.g. a transient error occurs due to a temporary network issue.

Failed Bucket

The source-controller may get stuck trying to produce an Artifact for a Bucket without completing. This can occur due to some of the following factors:

The object storage Endpoint is temporarily unavailable.
The specified object storage bucket does not exist.
The Secret reference contains a reference to a non-existing Secret.
The credentials in the referenced Secret are invalid.
The Bucket spec contains a generic misconfiguration.
A storage related failure when storing the artifact.

When this happens, the controller sets the Ready Condition status to False, and adds a Condition with the following attributes to the Bucket's .status.conditions:

type: FetchFailed | type: StorageOperationFailed
status: "True"
reason: AuthenticationFailed | reason: BucketOperationFailed

This condition has a "negative polarity", and is only present on the Bucket while the status value is "True". There may be more arbitrary values for the reason field to provide accurate reason for a condition.

While the Bucket has this Condition, the controller will continue to attempt to produce an Artifact for the resource with an exponential backoff, until it succeeds and the Bucket is marked as ready.

Note that a Bucket can be reconciling while failing at the same time, for example due to a newly introduced configuration issue in the Bucket spec.

Observed Generation

The source-controller reports an observed generation in the Bucket's .status.observedGeneration. The observed generation is the latest .metadata.generation which resulted in either a ready state, or stalled due to error it can not recover from without human intervention.

Last Handled Reconcile At

The source-controller reports the last reconcile.fluxcd.io/requestedAt annotation value it acted on in the .status.lastHandledReconcileAt field.

For practical information about this field, see triggering a reconcile.
