Backup job of helm jenkins failing for no reason - amazon-web-services

Question

I am using the official helm chart of Jenkins.
I have enabled backup and also provided backup credentials
Here is the relevant config in values.yaml
## Backup cronjob configuration
## Ref: https://github.com/maorfr/kube-tasks
backup:
# Backup must use RBAC
# So by enabling backup you are enabling RBAC specific for backup
enabled: true
# Used for label app.kubernetes.io/component
componentName: "jenkins-backup"
# Schedule to run jobs. Must be in cron time format
# Ref: https://crontab.guru/
schedule: "0 2 * * *"
labels: {}
annotations: {}
# Example for authorization to AWS S3 using kube2iam
# Can also be done using environment variables
# iam.amazonaws.com/role: "jenkins"
image:
repository: "maorfr/kube-tasks"
tag: "0.2.0"
# Additional arguments for kube-tasks
# Ref: https://github.com/maorfr/kube-tasks#simple-backup
extraArgs: []
# Add existingSecret for AWS credentials
existingSecret: {}
# gcpcredentials: "credentials.json"
## Example for using an existing secret
# jenkinsaws:
## Use this key for AWS access key ID
awsaccesskey: "AAAAJJJJDDDDDDJJJJJ"
## Use this key for AWS secret access key
awssecretkey: "frkmfrkmrlkmfrkmflkmlm"
# Add additional environment variables
# jenkinsgcp:
## Use this key for GCP credentials
env: []
# Example environment variable required for AWS credentials chain
# - name: "AWS_REGION"
# value: "us-east-1"
resources:
requests:
memory: 1Gi
cpu: 1
limits:
memory: 1Gi
cpu: 1
# Destination to store the backup artifacts
# Supported cloud storage services: AWS S3, Minio S3, Azure Blob Storage, Google Cloud Storage
# Additional support can added. Visit this repository for details
# Ref: https://github.com/maorfr/skbn
destination: "s3://jenkins-data/backup"
However the backup job fails as follows:
2020/01/22 20:19:23 Backup started!
2020/01/22 20:19:23 Getting clients
2020/01/22 20:19:26 NoCredentialProviders: no valid providers in chain. Deprecated.
For verbose messaging see aws.Config.CredentialsChainVerboseErrors
What is missing?

Answer 1

you must create secret which looks like this:
kubectl create secret generic jenkinsaws --from-literal=jenkins_aws_access_key=ACCESS_KEY --from-literal=jenkins_aws_secret_key=SECRET_KEY
then consume it like this:
existingSecret:
jenkinsaws:
awsaccesskey: jenkins_aws_access_key
awssecretkey: jenkins_aws_secret_key
where jenkins_aws_access_key/jenkins_aws_secret_key it's key of the secret

Answer 2

backup:
enabled: true
destination: "s3://jenkins-pumbala/backup"
schedule: "15 1 * * *"
env:
- name: "AWS_ACCESS_KEY_ID"
value: "AKIDFFERWT***D36G"
- name: "AWS_SECRET_ACCESS_KEY"
value: "5zGdfgdfgdf***************Isi"
