Welcome to Mockoon's official CLI, a lightweight and fast NPM package to deploy your mock APIs anywhere. Feed it with a Mockoon's export file, and you are good to go.
- Use your mocks in the CLI
- Mockoon's documentation
$ npm install -g @mockoon/cli
$ mockoon-cli COMMAND
Use your mocks in the CLI
The CLI currently supports only data files (exported or not) in Mockoon's format.
The CLI can import and migrate data from older versions of Mockoon. However, it doesn't alter the file you provide and only migrates a copy. If you created or exported your mock with a more recent version of the application, you need to update your CLI with the following command:
npm install -g @mockoon/cli.
Two methods are available to run your mocks with the CLI: directly using a Mockoon's environment file or an export file.
Use a Mockoon environment file (preferred method)
You can run your mock in one single step using the start command and replacing
~/path/to/your-environment-file.json by the actual location of your Mockoon environment file:
$ mockoon-cli start --data ~/path/to/your-environment-file.json
To locate your environment file from the main application, right-click on a environment and select "Show in folder" in the context menu.
Use a Mockoon export file
While we recommend using the method above to launch your mocks with the CLI, you can still use Mockoon's export feature. The advantage of this method is that it allows exporting multiple mocks and run them together with one start command and the
To export your environment(s) to use them in the CLI, follow these steps:
Import/exportapplication menu and choose
Mockoon's format -> Export all environments to a file (JSON)or
Mockoon's format -> Export current environment to a file (JSON).
You can also right-click on one of the environments and select
Copy to clipboard (JSON). You will then have to manually create a file and paste the environment's JSON data.
Choose a folder to save the JSON file.
Use the start command below to launch your mock APIs with the CLI:
$ mockoon-cli start --data ~/path/to/your-export-file.json -i 0
You will find more details in the official documentation.
Mockoon's CLI has been tested on Node.js versions 10, 12, 14, and 15.
mockoon-cli list [ID]
mockoon-cli stop [ID]
mockoon-cli help [COMMAND]
Starts a mock API from a Mockoon's environment file or export file. As an export file can contain multiple environments, you can indicate the one you want to run by specifying its index in the file or its name. If only one environment is present in the file, you can omit the index, and the CLI will run it by default.
The process will be created by default with the name and port of the Mockoon's environment. You can override these values by using the
USAGE $ mockoon-cli start OPTIONS -a, --all Run all environments -d, --data=data (required) Path or URL to your Mockoon file -i, --index=index Environment's index in the data file -n, --name=name Environment name in the data file -N, --pname=pname Override process name -p, --port=port Override environment's port -l, --hostname=0.0.0.0 Override default listening hostname (0.0.0.0) -h, --help show CLI help EXAMPLES $ mockoon-cli start --data ~/data.json $ mockoon-cli start --data ~/data.json --index 0 $ mockoon-cli start --data https://file-server/data.json --index 0 $ mockoon-cli start --data ~/data.json --name "Mock environment" $ mockoon-cli start --data ~/data.json --name "Mock environment" --pname "proc1" $ mockoon-cli start --data ~/data.json --all
mockoon-cli list [ID]
Lists all the running mock APIs and display some information: process name, pid, status, cpu, memory, port. You can also get the same information for a specific mock API by providing its pid or name.
USAGE $ mockoon-cli list ARGUMENTS ID Running API pid or name OPTIONS -h, --help show CLI help EXAMPLE $ mockoon-cli list $ mockoon-cli info $ mockoon-cli list 0 $ mockoon-cli list "Mock_environment"
mockoon-cli stop [ID]
Stops one or more running processes. When 'all' is provided, all processes will be stopped.
USAGE $ mockoon-cli stop [ID] ARGUMENTS ID Running API pid or name OPTIONS -h, --help show CLI help EXAMPLE $ mockoon-cli stop $ mockoon-cli stop 0 $ mockoon-cli stop "name" $ mockoon-cli stop "all"
Generates a Dockerfile used to build a self-contained image of a mock API. After building the image, no additional parameters will be needed when running the container.
This command takes similar flags as the
Please note that this command will extract your Mockoon environment from the file you provide and put it side by side with the generated Dockerfile. Both files are required in order to build the image.
For more information on how to build the image: Using the dockerize command
USAGE $ mockoon-cli dockerize OPTIONS -d, --data=data (required) Path or URL to your Mockoon file -i, --index=index Environment's index in the data file -n, --name=name Environment name in the data file -p, --port=port Override environment's port -o, --output Generated Dockerfile path and name (e.g. `./Dockerfile`) -h, --help show CLI help EXAMPLES $ mockoon-cli dockerize --data ~/data.json --output ./Dockerfile $ mockoon-cli dockerize --data ~/data.json --index 0 --output ./Dockerfile $ mockoon-cli dockerize --data https://file-server/data.json --index 0 --output ./Dockerfile $ mockoon-cli dockerize --data ~/data.json --name "Mock environment" --output ./Dockerfile
mockoon-cli help [COMMAND]
Returns information about a command.
USAGE $ mockoon-cli help [COMMAND] ARGUMENTS COMMAND command to show help for OPTIONS --all see all commands in CLI
Using the generic Docker image
A generic Docker image is published on the Docker Hub Mockoon CLI repository. It uses
node:14-alpine and installs the latest version of Mockoon CLI.
mockoon-cli start flags (
--index, etc.) must be provided when running the container.
To load the Mockoon data, you can either mount a local data file and pass
mockoon-cli start flags at the end of the command:
docker run -d --mount type=bind,source=/home/your-data-file.json,target=/data,readonly -p 3000:3000 mockoon/cli:latest -d data -i 0 -p 3000
Or directly pass a URL to the
mockoon-cli start command, without mounting a local data file:
docker run -d -p 3000:3000 mockoon/cli:latest -d https://raw.githubusercontent.com/mockoon/mock-samples/main/samples/generate-mock-data.json -i 0 -p 3000
You can use the
dockerize command to generate a new Dockerfile that will allow you to build a self-contained image. Thus, no Mockoon CLI specific parameters will be needed when running the container.
mockoon-cli dockerize --data ./sample-data.json --port 3000 --index 0 --output ./tmp/Dockerfile
navigate to the
tmpfolder, where the Dockerfile has been generated:
Build the image:
docker build -t mockoon-mock1 .
Run the container:
docker run -d -p <host_port>:3000 mockoon-mock1
Logs are located in
error.log file contains mostly server errors that occur at startup time and prevent the mock API to run (port already in use, etc.). They shouldn't occur that often.
out.log file contains all other log entries (all levels) produced by the running mock server. Most of the errors occurring in Mockoon CLI (or the main application) are not critical and therefore considered as normal output. As an example, if the JSON body from an entering request is erroneous, Mockoon will log a JSON parsing error, but it won't block the normal execution of the application.
Mockoon CLI uses PM2 to start, stop or list the running mock APIs. Therefore, you can directly use PM2 commands to manage the processes.
You will find Mockoon's documentation on the official website. It covers the most complex features.
You can discuss all things related to Mockoon's CLI, and ask for help, on the official community. It's also a good place to discuss bugs and feature requests before opening an issue on this repository. For more chat-like discussions, you can also join our Discord server.
