ES Admin UI with multiple indices support [FE]

Denys Mishunov requested to merge es-admin-step2-fe into es-admin-step2

What does this MR do?

Introduces brand-new Vue application for Elasticsearch Admin UI with support for multiple indices. Please, reference:

for more information.

With some exceptions, eventually branched off into the follow-up issues, this MR provides support for Step 2: Support multiple indices to Elasticsearch Admin options.

⚠ This MR should not be merged and will be picked up by Search group whenever it fits the schedule.

Automated tests

There are quite a few test failures for now due to WIP nature of this MR. Also, this MR is part of a bigger picture with BE involved in its own MR and those other parts are not necessarily ready yet.

  • ee/spec/elastic_integration will be taken care of at a later point, when API is settled
  • This might require new QA tests (there are none for Elasticsaearch so far)

How to click-test?

IMPORTANT Make sure you have Elasticsearch installed and running in your gdk before testing.

Adding a new index

  • Go to Admin Area → Elasticsearch
  • If you don't have any GitLab index from before, an empty state screen will be shown with Create new GitLab index button
  • If you did have any index from before, you will be presented with the list of existing indices with Add GitLab index button above the list to the right

Pausing indexing

  • While on the indices list, click Pause indexing.
    • NOTE: if instead, you see a green Resume Indexing button, this means the indexing is not running atm
  • A modal will be shown with explanatory text and orange Pause indexing button at the bottom
  • Click the Pause indexing button in the modal
  • The modal gets dismissed
  • The Pause indexing gets replaced with the green Resume Indexing button

Resuming indexing

  • While on the indices list, click the green Resume Indexing button.
  • A modal will be shown with explanatory text
  • If you want to perform a full reindexing after resuming the indexing, make sure the Reindex data after resuming to index is checked. However, it doesn't change anything in the UI
  • Click the Resume Indexing button in the modal
  • The modal gets dismissed
  • The green Resume Indexing gets replaced with the Pause indexing button

Global Reindexing

  • While on the indices list, click Reindex button
  • A modal will be shown with explanatory text and green Reindex button at the bottom
  • Click the Reindex button in the modal
  • The modal gets dismissed
  • If reindexing has been successfully initialized (not finished! as it might take several days) a corresponding message will be shown
  • If Indexing has been previously Paused (green Resume indexing button), Reindexing resumes indexing automatically
