ui: Enable recovery from an unreachable datacenter (500 error) (#7404)
For URL maintenance reasons we store the last visited DC in
localStorage incase you come back to a page (for example settings) that
doesn't have a dc in the URL.

A problem arises here if the last DC you tried to visit is unreachable.

The first fix here clears out the last visited DC from localStorage if
the API has errored out.

Secondly, our `href-mut` helper which mutates the current current and
replaces 'parts' in the URL rather than the whole thing functioned by
detecting the current route/URL you are on an 'mutating' that. A problem
arose here as even though you might be on the `/ui/dc-1/services` URL the
actual route is the 'error' route which does not have a URL that can be
changed properly.

The second fix here uses route.currentRoute.name over route.currentRouteName.

The latter is equal to error when an error occurs whereas the former gives you the name of the route before the error happened, which is actually what we want/the intent here.

ie. when `router.currentRouteName === 'error'` then
`router.currentRoute.name === Name Of Route Before It Errored` it seems

consul-ui

Prerequisites

You will need the following things properly installed on your computer.

Installation

  • git clone https://github.com/hashicorp/consul.git this repository
  • cd ui-v2
  • yarn install

All tooling scripts below primarily use make which in turn call node package scripts.

Running / Development

The source code comes with a small development mode that runs enough of the consul API as a set of mocks/fixtures to be able to run the UI without having to run consul.

To enable ACLs using the mock API, use Web Inspector to set a cookie as follows:

CONSUL_ACLS_ENABLE=1

This will enable the ACLs login page, to which you can login with any ACL token/secret.

You can also use a number of other cookie key/values to set various things whilst developing the UI, such as (but not limited to):

CONSUL_SERVICE_COUNT=1000
CONSUL_NODE_CODE=1000
// etc etc

See ./node_modules/@hashicorp/consul-api-double for more details.

If you wish to run the UI code against a running consul instance, uncomment the proxy line in .ember-cli to point ember-cli to your consul instance.

You can also run the UI against a normal Consul installation.

make start-consul or yarn run start:consul will use the CONSUL_HTTP_ADDR environment variable to locate the Consul installation. If that it not set start-consul will use http://localhost:8500.

Example usage:

CONSUL_HTTP_ADDR=http://10.0.0.1:8500 make start-consul

Code Generators

Make use of the many generators for code, try ember help generate for more details

Running Tests

Please note: You do not need to run make start-api/yarn run start:api to run the tests, but the same mock consul API is used.

  • make test or yarn run test
  • make test-view or yarn run test:view to view the tests running in Chrome

Linting

make lint currently runs linting on the majority of js files and hbs files (using ember-template-lint).

See .eslintrc.js and .eslintignore for specific configuration.

Building

  • make build builds the UI for production usage (env=production)
  • make build-ci builds the UI for CI/test usage (env=test)

Static files are built into ./dist

Running Tests in Parallel

Alternatively, ember-exam can be used to split the tests across multiple browser instances for faster results. Most options are the same as ember test. To see a full list of options, run ember exam --help.

Note: The EMBER_EXAM_PARALLEL environment variable must be set to override the default parallel value of 1 browser instance in testem.js.

To quickly run the tests across 4 parallel browser instances:

make test-parallel

To run manually:

$ EMBER_EXAM_PARALLEL=true ./node_modules/.bin/ember exam --split <num> --parallel

More ways to split tests can be found in the ember-exam README.md.
