Basic Usage

create a meilisearch service

# usage
dokku meilisearch:create <service> [--create-flags...]

flags:

• -c|--config-options "--args --go=here": extra arguments to pass to the container create command (default: None)
• -C|--custom-env "USER=alpha;HOST=beta": semi-colon delimited environment variables to start the service with
• -i|--image IMAGE: the image name to start the service with
• -I|--image-version IMAGE_VERSION: the image version to start the service with
• -m|--memory MEMORY: container memory limit in megabytes (default: unlimited)
• -p|--password PASSWORD: override the user-level service password
• -r|--root-password PASSWORD: override the root-level service password
• -s|--shm-size SHM_SIZE: override shared memory size for meilisearch docker container

Create a meilisearch service named lollipop:

dokku meilisearch:create lollipop

You can also specify the image and image version to use for the service. It must be compatible with the getmeili/meilisearch image.

export MEILISEARCH_IMAGE="getmeili/meilisearch"
export MEILISEARCH_IMAGE_VERSION="${PLUGIN_IMAGE_VERSION}"
dokku meilisearch:create lollipop

You can also specify custom environment variables to start the meilisearch service in semi-colon separated form.

export MEILISEARCH_CUSTOM_ENV="USER=alpha;HOST=beta"
dokku meilisearch:create lollipop

print the service information

# usage
dokku meilisearch:info <service> [--single-info-flag]

flags:

• --config-dir: show the service configuration directory
• --data-dir: show the service data directory
• --dsn: show the service DSN
• --exposed-ports: show service exposed ports
• --id: show the service container id
• --internal-ip: show the service internal ip
• --links: show the service app links
• --service-root: show the service root directory
• --status: show the service running status
• --version: show the service image version

Get connection information as follows:

dokku meilisearch:info lollipop

You can also retrieve a specific piece of service info via flags:

dokku meilisearch:info lollipop --config-dir
dokku meilisearch:info lollipop --data-dir
dokku meilisearch:info lollipop --dsn
dokku meilisearch:info lollipop --exposed-ports
dokku meilisearch:info lollipop --id
dokku meilisearch:info lollipop --internal-ip
dokku meilisearch:info lollipop --links
dokku meilisearch:info lollipop --service-root
dokku meilisearch:info lollipop --status
dokku meilisearch:info lollipop --version

list all meilisearch services

# usage
dokku meilisearch:list 

List all services:

dokku meilisearch:list

print the most recent log(s) for this service

# usage
dokku meilisearch:logs <service> [-t|--tail] <tail-num-optional>

flags:

• -t|--tail [<tail-num>]: do not stop when end of the logs are reached and wait for additional output

You can tail logs for a particular service:

dokku meilisearch:logs lollipop

By default, logs will not be tailed, but you can do this with the --tail flag:

dokku meilisearch:logs lollipop --tail

The default tail setting is to show all logs, but an initial count can also be specified:

dokku meilisearch:logs lollipop --tail 5

link the meilisearch service to the app

# usage
dokku meilisearch:link <service> <app> [--link-flags...]

flags:

• -a|--alias "BLUE_DATABASE": an alternative alias to use for linking to an app via environment variable
• -q|--querystring "pool=5": ampersand delimited querystring arguments to append to the service link

A meilisearch service can be linked to a container. This will use native docker links via the docker-options plugin. Here we link it to our playground app.

NOTE: this will restart your app

dokku meilisearch:link lollipop playground

The following environment variables will be set automatically by docker (not on the app itself, so they won’t be listed when calling dokku config):

DOKKU_MEILISEARCH_LOLLIPOP_NAME=/lollipop/DATABASE
DOKKU_MEILISEARCH_LOLLIPOP_PORT=tcp://172.17.0.1:7700
DOKKU_MEILISEARCH_LOLLIPOP_PORT_7700_TCP=tcp://172.17.0.1:7700
DOKKU_MEILISEARCH_LOLLIPOP_PORT_7700_TCP_PROTO=tcp
DOKKU_MEILISEARCH_LOLLIPOP_PORT_7700_TCP_PORT=7700
DOKKU_MEILISEARCH_LOLLIPOP_PORT_7700_TCP_ADDR=172.17.0.1

The following will be set on the linked application by default:

MEILISEARCH_URL=http://lollipop:SOME_PASSWORD@dokku-meilisearch-lollipop:7700/lollipop

The host exposed here only works internally in docker containers. If you want your container to be reachable from outside, you should use the expose subcommand. Another service can be linked to your app:

dokku meilisearch:link other_service playground

It is possible to change the protocol for MEILISEARCH_URL by setting the environment variable MEILISEARCH_DATABASE_SCHEME on the app. Doing so will after linking will cause the plugin to think the service is not linked, and we advise you to unlink before proceeding.

dokku config:set playground MEILISEARCH_DATABASE_SCHEME=http2
dokku meilisearch:link lollipop playground

This will cause MEILISEARCH_URL to be set as:

http2://lollipop:SOME_PASSWORD@dokku-meilisearch-lollipop:7700/lollipop

unlink the meilisearch service from the app

# usage
dokku meilisearch:unlink <service> <app>

You can unlink a meilisearch service:

NOTE: this will restart your app and unset related environment variables

dokku meilisearch:unlink lollipop playground

Service Lifecycle

The lifecycle of each service can be managed through the following commands:

enter or run a command in a running meilisearch service container

# usage
dokku meilisearch:enter <service>

A bash prompt can be opened against a running service. Filesystem changes will not be saved to disk.

NOTE: disconnecting from ssh while running this command may leave zombie processes due to moby/moby#9098

dokku meilisearch:enter lollipop

You may also run a command directly against the service. Filesystem changes will not be saved to disk.

dokku meilisearch:enter lollipop touch /tmp/test

expose a meilisearch service on custom host:port if provided (random port on the 0.0.0.0 interface if otherwise unspecified)

# usage
dokku meilisearch:expose <service> <ports...>

Expose the service on the service's normal ports, allowing access to it from the public interface (0.0.0.0):

dokku meilisearch:expose lollipop 7700

Expose the service on the service's normal ports, with the first on a specified ip adddress (127.0.0.1):

dokku meilisearch:expose lollipop 127.0.0.1:7700

unexpose a previously exposed meilisearch service

# usage
dokku meilisearch:unexpose <service>

Unexpose the service, removing access to it from the public interface (0.0.0.0):

dokku meilisearch:unexpose lollipop

promote service as MEILISEARCH_URL in

# usage
dokku meilisearch:promote <service> <app>

If you have a meilisearch service linked to an app and try to link another meilisearch service another link environment variable will be generated automatically:

DOKKU_MEILISEARCH_BLUE_URL=http://other_service:ANOTHER_PASSWORD@dokku-meilisearch-other-service:7700/other_service

You can promote the new service to be the primary one:

NOTE: this will restart your app

dokku meilisearch:promote other_service playground

This will replace MEILISEARCH_URL with the url from other_service and generate another environment variable to hold the previous value if necessary. You could end up with the following for example:

MEILISEARCH_URL=http://other_service:ANOTHER_PASSWORD@dokku-meilisearch-other-service:7700/other_service
DOKKU_MEILISEARCH_BLUE_URL=http://other_service:ANOTHER_PASSWORD@dokku-meilisearch-other-service:7700/other_service
DOKKU_MEILISEARCH_SILVER_URL=http://lollipop:SOME_PASSWORD@dokku-meilisearch-lollipop:7700/lollipop

start a previously stopped meilisearch service

# usage
dokku meilisearch:start <service>

Start the service:

dokku meilisearch:start lollipop

stop a running meilisearch service

# usage
dokku meilisearch:stop <service>

Stop the service and the running container:

dokku meilisearch:stop lollipop

graceful shutdown and restart of the meilisearch service container

# usage
dokku meilisearch:restart <service>

Restart the service:

dokku meilisearch:restart lollipop

upgrade service to the specified versions

# usage
dokku meilisearch:upgrade <service> [--upgrade-flags...]

flags:

• -c|--config-options "--args --go=here": extra arguments to pass to the container create command (default: None)
• -C|--custom-env "USER=alpha;HOST=beta": semi-colon delimited environment variables to start the service with
• -i|--image IMAGE: the image name to start the service with
• -I|--image-version IMAGE_VERSION: the image version to start the service with
• -R|--restart-apps "true": whether to force an app restart
• -s|--shm-size SHM_SIZE: override shared memory size for meilisearch docker container

You can upgrade an existing service to a new image or image-version:

dokku meilisearch:upgrade lollipop

Service Automation

Service scripting can be executed using the following commands:

list all meilisearch service links for a given app

# usage
dokku meilisearch:app-links <app>

List all meilisearch services that are linked to the playground app.

dokku meilisearch:app-links playground

check if the meilisearch service exists

# usage
dokku meilisearch:exists <service>

Here we check if the lollipop meilisearch service exists.

dokku meilisearch:exists lollipop

check if the meilisearch service is linked to an app

# usage
dokku meilisearch:linked <service> <app>

Here we check if the lollipop meilisearch service is linked to the playground app.

dokku meilisearch:linked lollipop playground

list all apps linked to the meilisearch service

# usage
dokku meilisearch:links <service>

List all apps linked to the lollipop meilisearch service.

dokku meilisearch:links lollipop

Disabling docker pull calls

If you wish to disable the docker pull calls that the plugin triggers, you may set the MEILISEARCH_DISABLE_PULL environment variable to true. Once disabled, you will need to pull the service image you wish to deploy as shown in the stderr output.

Please ensure the proper images are in place when docker pull is disabled.
