Where i have to install Add-ons on Plone

I'm new on Plone, and i'm following Plone Training tutorial. I'm trying Plone with Docker image

But in step 13, extending with new components, i don't know surely where i have to install the new packages, i try it on different sections:

buildout.cfg:

[plonesite]
  eggs =
    collective.easyform
    plone.app.mosaic

[instance]
  eggs =
    collective.easyform
    plone.app.mosaic

[versions]
  collective.easyform = 2.1.5
  plone.app.mosaic = 2.2.2

I can't get those packages appears on /@@overview-controlpanel to activate them.

Anybody could help me please ? Thanks in advanced.

Either you defines your eggs globally in the buildout section and reference it within the instance section like:

[buildout]

eggs = 
  .....

[instance]
eggs = ${buildout.eggs}

So adding an add-on in the buildout -> eggs option in this case is enough.

The [instance]-part is missing the recipe: recipe = plone.recipe.zope2instance

I suggest you read https://training.plone.org/5/mastering-plone/buildout_1.html to learn bout the basics of configuring Plone with buildout.
