lpn (Liferay Portal Nook)

Codecov Coverage Go Report Card

This is LPN https://mdelapenya.github.io/lpn/index.html, a CLI that makes it easy running Liferay Portal's Docker images.

It wraps Docker commands so you just have to run this tool, and pass the specific tag you want to run.

Requirements

You have to install Docker on your machine first. Check this guide.

Installation

For current stable version of lpn, please visit downloads page, and select the target platform, based on O.S. and architecture.

If you are in the Golang world, you could install this tool from source code.

For that reason you need to:

Now you can use lpn from your command line.

Tool Configuration

lpn uses a configuration file in YAML format for the values that could be modified by end-users, like the container names, or the images to be used with each type.

If the configuration file is not present at $HOME/.lpn/config.yml, lpn will create it the first time it is run.

An example of default values are:

container:
  names:
    db:
      ce: db-ce
      commerce: db-commerce
      dxp: db-dxp
      nightly: db-nightly
      release: db-release
    portal:
      ce: lpn-ce
      commerce: lpn-commerce
      dxp: lpn-dxp
      nightly: lpn-nightly
      release: lpn-release
images:
  portal:
    ce:
      image: liferay/portal
      tag: 7.0.6-ga7
    commerce:
      image: liferay/commerce
      tag: 1.1.1
    dxp:
      image: liferay/dxp
      tag: 7.0.10.8
    nightly:
      image: mdelapenya/portal-snapshot
      tag: latest
    release:
      image: mdelapenya/liferay-portal
      tag: latest

A use case of overriding this configuration would be if you would like to update lpn to use a different tag on CE runs. Then, please go to the configuration file and update the proper key:

[...]
images:
  portal:
    ce:
      image: liferay/portal
      tag: 7.1.2-ga3
[...]

Tools logs

The CLI uses Logrus as default Logger, so it's possible to configure the logger using Logging levels to enrich the output of the tool.

To set the log level, please set the environment variable LPN_LOG_LEVEL to one of the following values, being INFO the default one:

$ export LPN_LOG_LEVEL=TRACE
$ export LPN_LOG_LEVEL=DEBUG
$ export LPN_LOG_LEVEL=INFO
$ export LPN_LOG_LEVEL=WARNING
$ export LPN_LOG_LEVEL=ERROR
$ export LPN_LOG_LEVEL=FATAL
$ export LPN_LOG_LEVEL=PANIC

It's also possible to add current timestamp to each log line. To do so, please set the environment variable LPN_LOG_INCLUDE_TIMESTAMP, with "true" (case-insensitive).

$ export LPN_LOG_INCLUDE_TIMESTAMP=TRUE
$ export LPN_LOG_INCLUDE_TIMESTAMP=true

What does lpn do?

With lpn you'll be able to:

Usage

The available capabilities present in the tool are the following:

Which are the available commands?

Execute lpn help to see the list of available commands. Each command could have subcommands, so append the help command to each subcommand and you'll get a list of options for each one.

This could be an example of how the help subcommand shows:

Use "lpn [command] --help" for more information about a command.

Once you have typed the proper command, to specify with which image type you want to execute the command, there are the following subcommands:

So any command needs the combination of one of the subcommands above. So to run a DXP image, you would need to execute lpn run dxp.

Running a container from a Liferay Portal/DXP image

It will run the desired image, pulling it first if it does not exist in your local Docker installation. To specify which image type you want to run, please select it adding the ce, dxp, release, nightly, commerce subcommands.

You will be able to configure in which state you want to run the image, using the following flags:

Flag Description
-d, --debug Enables debug mode. (default false)
-D, --debugPort Sets the debug port of Liferay Portal's bundle. It only applies if debug mode is enabled (default 9000)
-g, --gogoPort Sets the GoGo Shell port of Liferay Portal's bundle. (default 11311)
-p, --httpPort Sets the HTTP port of Liferay Portal's bundle. (default 8080)
-m, --memory Sets the memory for the JVM memory configuration of Liferay Portal's bundle. (default "-Xmx2048m" in the CE and DXP images, and "2048m" in the rest)
-P, --properties Sets the location of a portal-ext properties files to configure the running instance of Liferay Portal's bundle.
-s, --datastore Sets the default store type for the portal (default hsql). If the storeType command is different than "hsql", then lpn will try to spin up a container for the datastore, connected to the running portal instance. Available datastores are: hsql, mysql and postgresql.
-t, --tag Sets the image tag to run

Examples:

$ lpn run ce -t "7.1.1-ga2"
$ lpn run dxp --properties "/tmp/portal-ext.properties"
$ lpn run nightly
$ lpn run commerce --debug --httpPort 8081 --memory "Xmx8g"
$ lpn run commerce --debug --httpPort 8081 --store "hsql"

To specify to which image type you want to deploy, please select it adding the ce, dxp, release, nightly, commerce subcommands.

You will be able to configure which file or directory you want to deploy to the running container, using the following flags:

Flag Description
-d, --dir The directory to deploy its content. Only first-level files will be deployed, so no recursive deployment will happen
-f, --files The file or files to deploy. A comma-separated list of files is accepted to deploy multiple files at the same time

Examples:

$ lpn deploy ce --dir /tmp/modules-from-my-dev-team
$ lpn deploy nightly --files /tmp/moduleA.jar
$ lpn deploy commerce --files /tmp/moduleA.jar,/tmp/themeB.war

Displaying logs

This command does not accept any flag to configure its execution.

Examples:

$ lpn log ce
