Looker Deployer (aka 'ldeploy') is a command line tool to help move Looker objects across instances. This includes Content (Looks, Dashboards, entire Spaces, etc.), Boards and Connections.
As of 2023, Looker Deployer is supported, but not warrantied by Google. Issues and feature requests can be reported via https://github.com/llooker/looker_deployer/issues, which will be regularly monitored and prioritized.
In order for these commands to correctly work a few assumptions/requirements are needed for your environment:
- Python Looker Deployer requires Python 3.6-3.9
- Gazer The content deployment command makes use of gzr to automate content deployment, so you will need to have that installed and configured properly. Gazer requires an up-to-date version of ruby.
Looker Deployer makes use of the Looker SDK to
communicate with your Looker instances. A looker.ini
file is required to provide authentication. By default the tool
looks for this file in your working directory but if it is named differently or in a different location you can make use
of the --ini
argument to specify its location. Here's an example ini file:
[dev]
base_url=https://looker-dev.company.com:19999
client_id=abc
client_secret=xyz
verify_ssl=True
[prod]
base_url=https://looker-prod.company.com:19999
client_id=abc
client_secret=xyz
verify_ssl=True
Looker Deployer is on PyPi! - You can install it with pip install looker-deployer
.
A looker.ini
file is required for API authentication. You will have to either volume-map the ini file
when you run the container, or (recommended) build an image from this one that "burns" a relevant ini file into the
container.
To do this, create a directory with an looker.ini
file and a Dockerfile
with the following content:
FROM python:3.9-slim
RUN apt update
RUN apt -y install ruby ruby-dev
RUN gem install gazer
RUN apt -y install git
RUN git clone https://github.com/looker-open-source/looker_deployer.git
WORKDIR /looker_deployer
COPY looker.ini .
RUN pip install .
ENTRYPOINT ["ldeploy"]
Then simply:
docker build -t ldeploy .
You can get use: docker run ldeploy <command> <parameters> ...
Keep in mind that in order to get the output you will need to map local directories to directories in docker, so a real life usage might look like:
docker run \
-v /local/path/to/ldeploy/settings:/ldeploy_settings \
-v /local/path/to/ldeploy/output:/ldeploy_output \
ldeploy content export \
--ini /ldeploy_settins/looker.ini \
--local-target /ldeploy_output \
<additional parameters>
You would put your looker.ini
file in /local/path/to/ldeploy/settings
and the output generated by the commands would
be found in /local/path/to/ldeploy/output
.
It is recommended to set up a python virtual environment if you intend to use looker-deployer on your local machine rather than using the docker image. This will prevent other modules from creating conflicts with the looker-deployer install.
pyenv offers easy management of python versions and virtual environments.
Once pyenv is installed, install the desired version of Python and create the virtual environment named ldeploy:
pyenv install 3.8.3
pyenv virtualenv 3.8.3 ldeploy
Activate the virtual environment and install looker-deployer:
pyenv activate ldeploy
pip install looker-deployer
looker-deployer is now ready for use! Once you are finished, deactivate the virtual environment:
source deactivate
The tool is invoked with the ldeploy
command, followed by the relevant sub-command. The available sub-commands
are: boards
, code
, connections
, and content
.
Each sub-command can be configured with its relevant arguments, which can be reviewed with the -h
or --help
argument. For example:
ldeploy content -h
This command makes use of gazer
to either pull content from your dev Looker instance to a directory structure on your
local machine or deploy content from said directory structure to a specified Looker instance. The command can work for
specific sets of Looks or Dashboards or can work on entire folders - and will correctly create any folder it doesn't find
in the target instance.
The content command is further divided into two subcommands: export
and import
All content deployment tasks begin by exporting a representation of your development environment's content folder tree
to local disk. This is done with the export
command. This directory tree is then used in subsequent import commands to import
dashboards, looks, or the entire tree to another instance.
The command accepts the following arguments:
usage: ldeploy content export [-h] --env ENV [--ini INI] [--debug] --folders
FOLDERS [FOLDERS ...] --local-target
LOCAL_TARGET
optional arguments:
-h, --help show this help message and exit
--env ENV What environment to deploy from
--ini INI ini file to parse for credentials
--debug set logger to debug for more verbosity
--folders FOLDERS [FOLDERS ...]
What folders to export content from
--local-target LOCAL_TARGET
Local directory to store content
Once you have exported your content from your development environment you can use the import
command to bring it into
your production environment.
usage: ldeploy content import [-h] --env ENV [--ini INI] [--debug]
[--recursive] [--target-folder TARGET_FOLDER]
(--folders FOLDERS [FOLDERS ...] | --dashboards DASHBOARDS [DASHBOARDS ...] | --looks LOOKS [LOOKS ...])
optional arguments:
-h, --help show this help message and exit
--env ENV What environment to deploy to
--ini INI ini file to parse for credentials
--debug set logger to debug for more verbosity
--recursive Should folders deploy recursively
--target-folder TARGET_FOLDER
override the default target folder with a custom path
--folders FOLDERS [FOLDERS ...]
Folders to fully deploy
--dashboards DASHBOARDS [DASHBOARDS ...]
Dashboards to deploy
--looks LOOKS [LOOKS ...]
Looks to deploy
Import base folder Support has been added for importing contenting to base folders other than Shared. There are a few important notes to go along with that:
ldeploy content export --env dev --folders 1 --local-target ./foo/bar/
<- exports the Shared folder (id 1) and all sub-folders to the
directory location ./foo/bar/
ldeploy content export --env dev --folders 5 8 --local-target ./foo/bar/
<- exports folders 5 and 8 (and all of their sub-folders) to the
directory location ./foo/bar/
ldeploy content import --env prod --folders ./foo/bar/Shared/Public
<- deploys every piece of content in
Shared/Public
to the prod instanceldeploy content import --env prod --folders ./foo/bar/Shared/Public --recursive --target-folder Shared/FromDev/Public
<- deploys every piece of content in
Shared/Public
and all sub-folders to the prod instance in the Shared/FromDev/Public
folder.ldeploy content import --env prod --dashboards ./foo/bar/Shared/Public/Dashboard_1.json ./foo/bar/Shared/Restricted/Dashboard_2.json
<- deploys Dashboard1
and Dashboard2
to their respective folders in
the prod instanceldeploy content import --env prod --folders ./dev/Users --recursive --target-folder Users
<- deploys every piece of content in dev/Users
and all sub-folders to the prod instance in the Users
folderldeploy content import --env prod --folders "./dev/Embed Users" --recursive --target-folder "Embed Users"
<- deploys every piece of content in dev/Embed Users
and all sub-folders to the prod instance in the Embed Groups
folderldeploy content import --env prod --folders "./dev/Embed Groups" --recursive --target-folder "Embed Groups"
<- deploys every piece of content in dev/Embed Groups
and all sub-folders to the prod instance in the Embed Groups
folderThis command allows for the deployment of boards/homepages across instances. It attempts to resolve differences in
dashboard/look ids across instances and confirms that the content is present before building the new board. Boards are
matched by title - updating an existing board will result in the rebuilding of the relevant sections and items to
prevent issues with attempting to match via title. If needing to update a board title, make use of the title-change
parameter to allow the command to find the old title. The command accepts the following arguments:
usage: ldeploy boards [-h] --source SOURCE --target TARGET [TARGET ...]
--board BOARD [--ini INI] [--allow-partial]
[--title-change TITLE_CHANGE] [--debug]
optional arguments:
-h, --help show this help message and exit
--source SOURCE which environment to source the board from
--target TARGET [TARGET ...]
which target environment(s) to deploy to
--board BOARD which board to deploy
--ini INI ini file to parse for credentials
--allow-partial allow partial deployment of board content if not all
content is present on target instance?
--title-change TITLE_CHANGE
if updating title, the old title to replace in target
environments
--debug set logger to debug for more verbosity
ldeploy boards --source dev --target prod --board 'My Cool Board'
<- deploys the board 'My Cool Board' from
dev to prodldeploy boards --source dev --target prod_1 prod_2 --allow-partial --board 'My Updated Title Board' --title-change 'My Cool Board'
<- This deploys a board whose title has been changed from 'My Cool Board' to 'My Updated Title Board' from dev
to two instances: prod_1 and prod_2. Any content not present in either prod instance will be skipped without raising
any errors.This command allows for the migration of database connections across instances. For security purposes, Looker's API does
not transmit password credentials, so this command allows for the injection of these credentials from the .ini
file.
The command accepts the following arguments:
usage: ldeploy connections [-h] --source SOURCE [--ini INI] --target TARGET
[TARGET ...] [--pattern PATTERN]
[--include-password] [--debug]
optional arguments:
-h, --help show this help message and exit
--source SOURCE which environment to source the board from
--ini INI ini file to parse for credentials
--target TARGET [TARGET ...]
which target environment(s) to deploy to
--pattern PATTERN regex pattern to filter which connections are deployed
--include-password should passwords be set from the ini file?
--debug set logger to debug for more verbosity
ldeploy connections --source dev --target prod
<- This will deploy all connections in the dev instance to the prod
instance. No credentials will be included and would need to be manually added from the Looker UI.ldeploy connections --source dev --target prod --pattern ^bigquery --include-password
<- This will deploy all
connections that begin with bigquery
from dev to prod and attempt to inject passwords included in the .ini
file.This command will manage deployments of hub/spoke LookML code from the current Github master branch to the relevant production instance(s). This
is accomplished by sending a GET
request to each instances deploy endpoint and authenticating it with the webhook
secret.
An overview of the relevant architecture (click to embiggen):
In order to use the code deployment tool, a code_config.yaml
file is required. This file requires a list of instances - one
for each client production instance. This list must include the name (used to refer to that instance in the commands),
the endpoint, and the name of that instances spoke project. In addition, the config file requires an entry for the
common hub project and can optionally include a list of names to instance names to exclude from hub deployments. Here's
an example config:
instances:
- name: calvin
endpoint: https://looker-dev.company.com
spoke_project: powered_by_spoke_ck
- name: levis
endpoint: https://looker-dev.company.com
spoke_project: powered_by_spoke_lv
hub_project: powered_by_hub
The command accepts the following arguments:
usage: ldeploy code [-h] [--hub] [--spoke SPOKE [SPOKE ...]]
[--hub-exclude HUB_EXCLUDE [HUB_EXCLUDE ...]] [--debug]
optional arguments:
-h, --help show this help message and exit
--hub flag to deploy hub project
--spoke SPOKE [SPOKE ...]
which spoke(s) to deploy
--hub-exclude HUB_EXCLUDE [HUB_EXCLUDE ...]
which projects should be ignored from hub deployment
--debug set logger to debug for more verbosity
ldeploy code --hub
<- This will deploy the hub project to all production instancesldeploy code --spoke foo
<- This will deploy the spoke project named "foo" to the relevant instanceldeploy code --hub --spoke foo bar --hub-exclude bar --debug
<- This will deploy the hub project to all
instances except bar
and then deploy the spoke projects foo
and bar
to their respective instancesDue to the related nature of role settings in Looker, it is recommended to run these commands in the following order to ensure the prior information is available:
Special Considerations:
If you have externally manged groups, you will need to ensure you update for SAML/LDAP is done prior to Group in Group. These special groups are not migrated by the code referenced above.
