Note:
Ensure that the cluster has read and write access to the S3 buckets/Azure Blob storage container mentioned in DEFAULT_CACHE_BUCKET, DEFAULT_BUILD_LOGS_BUCKET or AZURE_BLOB_CONTAINER_CI_LOG, or AZURE_BLOB_CONTAINER_CI_CACHE.
Ensure that the cluster has read access to AWS secrets backends (SSM & secrets manager).

The following tables contain parameters and their details for Secrets and ConfigMaps that are configured during the installation of Devtron. If the installation is done using Helm, the values can be tweaked in values.yaml file.

We can use the --set flag to override the default values when installing with Helm. For example, to update POSTGRESQL_PASSWORD and BLOB_STORAGE_PROVIDER, use the install command as:

helm install devtron devtron/devtron-operator --create-namespace --namespace devtroncd \
--set secrets.POSTGRESQL_PASSWORD=change-me \
--set configs.BLOB_STORAGE_PROVIDER=S3

Configuration of Blob Storage

Blob Storage allows users to store large amounts of unstructured data. Unstructured data is a data that does not adhere to a particular data model or definition, such as text or binary data. Configuring blob storage in your Devtron environment allows you to store build logs and cache.

In case, if you do not configure the Blob Storage, then:

You will not be able to access the build and deployment logs after an hour.
Build time for commit hash takes longer as cache is not available.
Artifact reports cannot be generated in pre/post build and deployment stages.

You can configure Blob Storage with one of the following Blob Storage providers given below:

Note: You can also use the respective following command to switch to another Blob Storage provider. As an example, If you are using MinIO Storage and want to switch to Azure Blob Storage, use the command provided on the Azure Blob Storage tab to switch.

Use the following command to configure MinIO for storing logs and cache.

Note: Unlike global cloud providers such as AWS S3 Bucket, Azure Blob Storage and Google Cloud Storage, MinIO can be hosted locally also.

--reuse-values \
--set installer.modules={cicd} \
--set minio.enabled=true

Use the following command to configure AWS S3 bucket for storing build logs and cache. Refer to the AWS specific parameters on the Storage for Logs and Cache page.
