Linkerd CLI's "look and feel" is similar to Kubernetes kubectl CLI. Linkerd's dashboard can be extended to match Kubernetes dashboard UI.
This PR serves as a starting point for this work. The new sidebar shows all resources from all namespaces on initial page load. Resources can be filtered to show only items in a given namespace. The sidebar displays authority, deployment, service and, pod resources. We may need to think about whether it is necessary to show all resources types. Some resources, i.e. authorities, contain a large cardinality of resource details and may not be very useful to a user.

Includes a substantial refactor of Top.jsx to move the websocket
and top-request-aggregation code into a self-contained module
so that this code can be shared by /top and by each resource
detail page.
(This refactor also helps separate concerns in that
page; since that page also makes 10 second requests to the stat
api to populate the autocompletes in the form).
The TopModule uses the startTap prop to figure out whether it
should start a websocket connection and make a tap request
when mounted. (This is because the resource detail pages
start tapping immediately upon load, whereas /top can only
start once you've entered a query.
I've removed the spinner and the awaitingWebSocketConnection
state field because that now belongs in the top module. I think a
similar refactor of tap would be good before we re-add it.
Do a little more work to get the octopus graph closer to the mocks.
This version gives you a slightly better navigational sense of where
you are in the app, and gives you a clearer
view of the neighbouring stats
Add a basic top graph depicting the current resource's stats
and it's upstreams and downstreams.
Also add upstreams and downstreams tables for this resource
This will be styled more later, but just getting the basic components
and data onto the page.
Add a pod table to the Resource Detail page showing metrics
for pods belonging to a resource.
In the future, I think we'll modify the stat summary endpoint to
take multiple resources as arguments, and have the resource detail page
first query for the pods associated with the resource and then
query for stats for those pods.
See #1467 for discussion.
This PR also modifies the queries to not use the withREST component, in anticipation of the above changes.
This PR started out as a PR to link to our Resource Detail dashboard in
addition to grafana in the resource list pages, but I decided to refactor
the way we deal with our svgs since I was here.
This branch:
- modifies the GrafanaLink component to consist of the grafana icon
that links to grafana adds links to the ResourceDetail page in all our metrics tables
- adds a jsx component we can use to wrap svgs so that we don't get
annoying 404s on images that we have to handle
- remove the relative paths hack for images
- removes unused svg files in /img
Remove old unused graphs from the web code (scatter plot and line graph)
and their associated css
Files removed:
web/app/css/line-graph.css
web/app/css/list.css
web/app/css/scatterplot.css
web/app/css/version.css
web/app/js/components/LineGraph.jsx

Currently conduit stat outputs a column that shows the number of meshed pods in the resource being
queried. The web UI does not have this information about meshed pod state.
This commit adds a meshed column for better UI parity with the stat command.

Add a Top page to the linkerd web UI. This is the web equivalent of #1435.
I've used the same fields as in the current implementation.
This branch also includes some slight refactors to the Tap code to enable code reuse.
The request processing logic is pretty similar to that in Tap.jsx, except that we can
immediately discard the result once we receive the response end and aggregate
that result into the top results. So the index of tap results will tend to be smaller
(unless they're long running requests like streaming). But we also add a similar
index of aggregated Top results, and discard oldest results if top has been
running for a long time.
* Add a Top page to the web UI
* Refactor Tap event parsing into common util code
* Small refactors to the TapQueryForm and the CliCmd display to accomodate Top
* Collate tap events based on the ID (src, dst, stream)
* Also refactor keying of req/rsp/end into requestInit/responseInit/responseEnd for clarity
* Use pod labels when present in top
* Fix bug where src/dst were switched in the Tap display table
Tap.jsx is really large and contains a lot of logic that pertains only to the Tap Query Form.
This PR tries to separate the concerns of the form and the query display from the main
Tap querying and rendering logic.
This will also allow us to easily reuse this form/CLI formatting for the Top page.
Changes in this PR:
* moves all the code for the form into its own component (TapQueryForm)
* moves the code that displays the current query into its own component (TapQueryCliCmd)
* formats the current tap query as the equivalent command line format that you
can paste into a terminal
Now that we have source metadata in tap events, we can display
the pod name in the UI instead of the IP. I've also added a popover
that shows deploy and pod info if we have it.
Also adds another table in the expanded row view to show all the
metadata we have. This table probably won't stick around forever,
but I'm just displaying all the data we have right now.
We have a new format for displaying errors in ErrorBanner.
When a websocket error occurred, we'd pass in text where ErrorBanner
expects and object. This PR puts the websocket errors in an object
Also clean up the display of the error by removing redundant text.
Problem:
We depend on the websocketRequestSent bool (renamed to
tapRequestInProgress in this branch) to determine whether the
start/stop button says start or stop. However, we don't change
this value in setState until we open the websocket connection
(which could take some time). This led to a delay in when you
press the Start button and when it changes colour.
Solution:
Set the state before waiting for the websocket to open, so the
button colour changes immediately and the form feels more responsive
* Changing the statusText to be an object with more fields, then displaying them in the ErrorBanner

Problem:
Currently the web UI's resource autocomplete also lists authorities.
However you can't tap authorities in this way, you have to use --authority
in addition to whatever resource you're trying to tap.
The web UI is confusing as it presents authorities in that list.
Those authorities should instead be moved to the Authority box in the advanced filter form.
Solution:
* Don't present authorities as options in the Resource dropdowns
* Add authority autocomplete to authority form input
Follow up to @kl in #1391 there is an error when we try to tap an authority
Add client side filtering to the tap table, so that we can narrow down
queries while still tapping a whole resource.
There are two general kinds of filters here:
- filters where the number of possible values is bounded/small and
we know them (e.g. inbound/outbound, grpc status). here, I've tried to
hardcode the list of possible options with explanations (see the GRPC status filters)
- filters where the number of possible values can be very large (e.g. paths)
here, I've generated the list of options as we process the incoming data.
I also periodically delete the oldest filter option so the list of filters
doesn't grow unbounded
Filters added:
- GRPC status code filters
- http status filters
- path filters
- scheme filters
- tls, destination and source filters
* Make use of the Web UI to render tap events in a table
- Return JSON tap events instead of the command line output
- Experiment with a different way of rendering the EventList
- changed the default width back to 100% of the screen because this
table does not look great squished
* Update ant to 3.7.2
* Add autocomplete of namespaces/resources to Tap in web ui
* Add form fields for authority/path/method/rps/scheme
* Add the ability to clear error messages to the error banner
* Add error listener to ws object
Adds a tap endpoint in the web api that communicates with the dashboard
via websockets.
I've moved a bunch of code from the cli tap.go into utils so that the code
can be shared between web and CLI. I think we should consider making the
display more suited to web, but in the short term, reusing the CLI's
rendering of tap events works.
Adds a Tap page in the Web UI that you can use to make tap requests.
The form currently only allows you to enter a resource and namespace,
other filters coming in a follow-up branch.

This PR adjusts the colour of a popup in the sidebar, as well as removes
references to conduit in the frontend test fixtures.
All that's left in the Web UI code now is a few references to the conduit sites / githubs,
as well as the CLI name.
* Remove a touch of conduit blue from the sidebar popup
* Remove minor references to conduit throughout the web code
* Fully colour the sidebar in new bg colour
This PR begins to migrate Conduit to Linkerd2:
* The proxy has been completely removed from this repo, and is now located at
github.com/linkerd/linkerd2-proxy.
* A `Dockerfile-proxy` has been added to fetch the most-recently published proxy
binary from build.l5d.io.
* Proxy-specific protobuf bindings have been moved to
github.com/linkerd/linkerd2-proxy-api.
* All docker images now use the gcr.io/linkerd-io registry.
* `inject` now uses `LINKERD2_PROXY_` environment variables
* Go paths have been updated to reflect the new (future) repo location.
This PR starts removing all references to the word "Conduit" in the web UI.
In the interest of not making huge changes all at once, I'll gradually start moving away
from the usage of "conduit" in the Web UI. For example, there are a lot of components that
have conduit in their names but they don't need to.
This branch is mostly component / variable names. There should be no visible changes except
the spinner is no longer a Conduit spinner.
See #1262 for visible branding changes.
- Rename ConduitLink to PrefixedLink
- Remove ConduitSpinner in favour of antd.Spin
- Remove css classnames that are conduit- centered
- Parameterize the current Product Name so that it's easier to change in the future

- Add Reason to the error data passed from the api
- Rewrite error logic in the UI to try to make it clearer
- Show 0/0 pods meshed instead of 0/0 pods meshed (N/A) if 0 pods are meshed

- Adds a --namespace filter to conduit get pods
- Adds pod uptimes to the controller component toolitps on the ServiceMesh page
- Moves the ServiceMesh page back to using /api/pods
Adds the ability to query by a new non-kubernetes resource type, "authorities",
in the StatSummary api.
This includes an extensive refactor of stat_summary.go to deal with non-kubernetes
resource types.
- Add documentation to Resource in the public api so we can use it for authority
- Handle non-k8s resource requests in the StatSummary endpoint
- Rewrite stat summary fetching and parsing to handle non-k8s resources
- keys stat summary metric handling by Resource instead of a generated string
- Adds authority to the CLI
- Adds /authorities to the Web UI
- Adds some more stat integration and unit tests
Add Sidebar links to Pods, Deployments, and Replication Controllers
In #1016 we removed the sidebar links to individual resource pages in favour of a namespace
page that lists all resources. These resource pages require no additional code so they're still
in our UI (accessible under /pods, /deployments etc), just not easily findable. I find them
useful to check when in development mode, or when debugging something, so I'd like to
re-add links.
If we don't want them in permanently, we can gate them behind `NODE_ENV=development`
Don't allow the CLI or Web UI to request named resources if --all-namespaces is used.
This follows kubectl, which also does not allow requesting named resources
over all namespaces.
This PR also updates the Web API's behaviour to be in line with the CLI's.
Both will now default to the default namespace if no namespace is specified.
- If error messages are very long, truncate them and display a toggle to show the full message
- Tweak the headings - remove Pod, Container and Image - instead show them as titles
- Also move over from using Ant's Modal.method to the plain Modal component, which is a
little simpler to hook into our other renders.
* Display proxy container errors in the Web UI
Add an error modal to display pod errors
Add icon to data tables to indicate errors are present
Display errors on the Service Mesh Overview Page and all the resource pages
Add an emitWarning to the webpack config so that webpack will compile despite lint
errors when running in development mode. This is necessary to enable development
on the frontend using webpack-dev-server's automatic reloading.
Also sets a NODE_ENV in travis.yml so that the build will fail if linting fails.
