Command Line Interface (CLI)¶
From CKAN 2.9 onwards the CKAN configuration file is named ‘ckan.ini’. Previous names: ‘production.ini’ and ‘development.ini’ (plus others) may also still appear in documentation and the software. These legacy names will eventually be phased out.
From CKAN 2.9 onwards, the
paster command used for common CKAN
administration tasks has been replaced with the
If you have trouble running ‘ckan’ CLI commands, see Troubleshooting ckan Commands below.
Once you activate your CKAN virtualenv the “ckan” command is available from within any location within the host environment.
To run a ckan command without activating the virtualenv first, you have to give the full path the ckan script within the virtualenv, for example:
/usr/lib/ckan/default/bin/ckan -c /etc/ckan/default/ckan.ini user list
In the example commands below, we assume you’re running the commands with your virtualenv activated and from your ckan directory.
The general form of a CKAN
ckan command is:
ckan --config=/etc/ckan/default/ckan.ini command
The `` –config`` option tells CKAN where to find your config file, which it
reads for example to know which database it should use. As you’ll see in the
examples below, this option can be given as
-c for short.
The config file (ckan.ini) will generally be located in the
/etc/ckan/default/ directory however it can be located in any directory on
the host machine
command should be replaced with the name of the CKAN command that you wish to execute. Most commands have their own subcommands and options.
You may also specify the location of your config file using the CKAN_INI environment variable. You will no longer need to use –config= or -c to tell ckan where the config file is:
You can run the ckan command in the same directory as the CKAN config file when the config file is named ‘ckan.ini’. You will not be required to use –config or -c in this case. For backwards compatibility, the config file can be also named ‘development.ini’, but this usage is deprecated and will be phased out in a future CKAN release.
cd /usr/lib/ckan/default/src/ckan; ckan command
Commands and Subcommands
ckan -c /etc/ckan/default/ckan.ini user list
user is the name of the CKAN command you’re running, and
a subcommand of
For a list of all available commands, see CKAN Commands Reference.
Each command has its own help text, which tells you what subcommands and
options it has (if any). To print out a command’s help text, run the command
--help option, for example:
ckan -c /etc/ckan/default/ckan.ini user --help
Troubleshooting ckan Commands¶
If you receive ‘Permission Denied’ error, try running ckan with sudo.
sudo /usr/lib/ckan/default/bin/ckan -c /etc/ckan/default/ckan.ini db clean
Virtualenv not activated, or not in ckan dir¶
Most errors with ckan commands can be solved by remembering to activate your virtual environment and change to the ckan directory before running the command:
. /usr/lib/ckan/default/bin/activate cd /usr/lib/ckan/default/src/ckan
Error messages such as the following are usually caused by forgetting to do this:
- Command ‘foo’ not known (where foo is the name of the command you tried to run)
- The program ‘ckan’ is currently not installed
- Command not found: ckan
- ImportError: No module named fanstatic (or other
Running ckan commands provided by extensions¶
If you’re trying to run a CKAN command provided by an extension that you’ve installed and you’re getting an error like Command ‘foo’ not known even though you’ve activated your virtualenv, make sure that you have added the relevant plugin to the ckan.plugins setting in the ini file.
Wrong config file path¶
- AssertionError: Config filename development.ini does not exist
- This means you forgot to give the
-coption to tell CKAN where to find your config file. (CKAN looks for a config file named
development.iniin your current working directory by default.)
- ConfigParser.MissingSectionHeaderError: File contains no section headers
- This happens if the config file that you gave with the
--configoption is badly formatted, or if you gave the wrong filename.
- IOError: [Errno 2] No such file or directory: ‘…’
- This means you gave the wrong path to the
-coption (you gave a path to a file that doesn’t exist).

jobs command can be used to manage Background jobs.
New in version 2.7.
Run a background job worker¶
ckan -c /etc/ckan/default/ckan.ini jobs worker [--burst] [QUEUES]
Starts a worker that fetches job from the job queues and executes them. If no queue names are given then it listens to the default queue. This is equivalent to
ckan -c /etc/ckan/default/ckan.ini jobs worker default
If queue names are given then the worker listens to those queues and only those:
ckan -c /etc/ckan/default/ckan.ini jobs worker my-custom-queue another-special-queue
Hence, if you want the worker to listen to the default queue and some others then you must list the default queue explicitly
ckan -c /etc/ckan/default/ckan.ini jobs worker default my-custom-queue
--burst option is given then the worker will exit as soon as all its
queues are empty. Otherwise it will wait indefinitely until a new job is
enqueued (this is the default).
In a production setting you should use a more robust way of running background workers.
List enqueued jobs¶
ckan -c /etc/ckan/default/ckan.ini jobs list [QUEUES]
Lists the currently enqueued jobs from the given job queues. If no queue names are given then the jobs from all queues are listed.
Show details about a job¶
ckan -c /etc/ckan/default/ckan.ini jobs show ID
Shows details about the enqueued job with the given ID.
Cancel a job¶
ckan -c /etc/ckan/default/ckan.ini jobs cancel ID
Cancels the enqueued job with the given ID. Jobs can only be canceled while they are enqueued. Once a worker has started executing a job it cannot be aborted anymore.
Clear job queues¶
ckan -c /etc/ckan/default/ckan.ini jobs clear [QUEUES]
Cancels all jobs on the given job queues. If no queues are given then all queues are cleared.
Enqueue a test job¶
ckan -c /etc/ckan/default/ckan.ini jobs test [QUEUES]
Enqueues a test job. If no job queues are given then the job is added to the default queue. If queue names are given then a separate test job is added to each of the queues.
less: Compile all root less documents into their CSS counterparts¶
ckan minify [--clean] PATH - remove any minified files in the path
ckan -c /etc/ckan/default/ckan.ini minify ckan/public/base ckan -c /etc/ckan/default/ckan.ini minify ckan/public/base/css/*.css ckan -c /etc/ckan/default/ckan.ini minify ckan/public/base/css/red.css
If the –clean option is provided any minified files will be removed.
notify: Send out modification notifications¶
ckan notify replay - send out modification signals. In "replay" mode, an update signal is sent for each dataset in the database.
plugin-info: Provide info on installed plugins¶
As the name suggests, this commands shows you the installed plugins (based on the .ini file) , their description, and which interfaces they implement
profile: Code speed profiler¶
Provide a ckan url and it will make the request and record how long each function call took in a file that can be read by runsnakerun.
ckan profile URL
The result is saved in profile.data.search. To view the profile in runsnakerun:
You may need to install the cProfile python module.
run: Start Development server¶
ckan run --host (-h) - Set Host ckan run --port (-p) - Set Port ckan run --disable-reloader (-r) - Use reloader ckan run --passthrough_errors - Crash instead of handling fatal errors
--passthrough-errors to enable pdb¶
Exceptions are caught and handled by CKAN. Sometimes, user needs to disable
this error handling, to be able to use
pdb or the debug capabilities of the
most common IDE. This allows to use breakpoints, inspect the stack frames and
evaluate arbitrary Python code.
Running CKAN with
--passthrough-errors will automatically disable CKAN
reload capabilities and run everything in a single process, for the sake of
python -m pdb ckan run –passthrough-errors
search-index: Search index commands¶
ckan search-index check - Check search index ckan search-index clear - Clear the search index ckan search-index rebuild - Rebuild search index ckan search-index rebuild-fast - Reindex with multiprocessing ckan search-index show - Show index of a dataset
search-index: Rebuild search index¶
Rebuilds the search index. This is useful to prevent search indexes from getting out of sync with the main database.
ckan -c /etc/ckan/default/ckan.ini search-index rebuild
This default behaviour will clear the index and rebuild it with all datasets. If you want to rebuild it for only one dataset, you can provide a dataset name
ckan -c /etc/ckan/default/ckan.ini search-index rebuild test-dataset-name
Alternatively, you can use the -o or –only-missing option to only reindex datasets which are not already indexed
ckan -c /etc/ckan/default/ckan.ini search-index rebuild -o
If you don’t want to rebuild the whole index, but just refresh it, use the -r or –refresh option. This won’t clear the index before starting rebuilding it
ckan -c /etc/ckan/default/ckan.ini search-index rebuild -r
There is also an option available which works like the refresh option but tries to use all processes on the computer to reindex faster
ckan -c /etc/ckan/default/ckan.ini search-index rebuild-fast
There are other search related commands, mostly useful for debugging purposes
ckan search-index check - checks for datasets not indexed ckan search-index show DATASET_NAME - shows index of a dataset ckan search-index clear [DATASET_NAME] - clears the search index for the provided dataset or for the whole ckan instance
seed: Create test data in the database¶
basic - annakarenina and warandpeace. family - package relationships data. gov - government style data. hierarchy - hierarchy of groups. search - realistic data to test search. translations - test translations of terms. user - create a user "tester" with api key "tester". vocabs - some test vocabularies.
ckan -c /etc/ckan/default/ckan.ini seed basic
sysadmin: Give sysadmin rights¶
ckan sysadmin add - convert user into a sysadmin ckan sysadmin list - list sysadmins ckan sysadmin remove - removes user from sysadmins
For example, to make a user called ‘admin’ into a sysadmin
ckan -c /etc/ckan/default/ckan.ini sysadmin add admin
tracking: Update tracking statistics¶
ckan tracking update [start_date] - update tracking stats ckan tracking export FILE [start_date] - export tracking stats to a csv file
translation: Translation helper functions¶
regenerated if necessary when CKAN is started. Hence you usually do not
need to run
ckan translation js manually.
user: Create and manage users¶
Lets you create, remove, list and manage users.
ckan user add - add new user ckan user list - list all users ckan user remove - remove user ckan user setpass - set password for the user ckan user show - show user
For example, to create a new user called ‘admin’
ckan -c /etc/ckan/default/ckan.ini user add admin
To delete the ‘admin’ user
ckan -c /etc/ckan/default/ckan.ini user remove admin
views: Create views on relevant resources¶
ckan views clean - permanently delete views for all types no... ckan views clear - permanently delete all views or the ones with... ckan views create - create views on relevant resources. ckan views --dataset (-d) - Set Dataset ckan views --no-default-filters ckan views --search (-s) - Set Search ckan views --yes (-y)
