|
||||
|
||||
You can use the following ENV variables to customize the build:
|
||||
SRC_ORG Which fork of netbox to use (i.e. github.com/\${SRC_ORG}/\${SRC_REPO}).
|
||||
Default: netbox-community
|
||||
SRC_REPO The name of the repository to use (i.e. github.com/\${SRC_ORG}/\${SRC_REPO}).

Must not be outside of the netbox-docker repository (because of Docker)!
|
||||
Default: .netbox

|
||||
This may be useful, if you are manually managing the NETBOX_PATH.
|
||||
Default: undefined

Default:
|
||||
When <branch>=master: latest

Example: clever_lovelace
|
||||
Default: undefined

|
||||
'netboxcommunity/netbox:snapshot'.
|
||||
${0} v2.6.6
|
||||
This will fetch the 'v2.6.6' tag, build a Docker Image and tag it
