# The images can be pushed to any docker/image registeries
# like docker hub, quay. The registries are specified in
# the `build/push` script.
#
# The images of a project or company can then be grouped
# or hosted under a unique organization key like `openebs`
#
# Each component (container) will be pushed to a unique
# repository under an organization.
# Putting all this together, an unique uri for a given
# image comprises of:
#   <registry url>/<image org>/<image repo>:<image-tag>
#
# IMAGE_ORG can be used to customize the organization
# under which images should be pushed.
# By default the organization name is `openebs`.

## Currently we are running with Default options + other options
## Explanation for explicitly mentioned linters:
## exportloopref: checks for pointers to enclosing loop variables
## dupl: Tool for code clone detection within repo
## revive: Drop-in replacement of golint. It allows to enable or disable
##         rules using configuration file.
## bodyclose: checks whether HTTP response body is closed successfully
## goconst: Find repeated strings that could be replaced by a constant
## misspell: Finds commonly misspelled English words in comments
##
## NOTE: Disabling structcheck since it is reporting false positive cases
##       for more information look at https://github.com/golangci/golangci-lint/issues/537
