Problem:
In #2532 I removed the Tap/Top tables if there was no http traffic, but the
check I used depended on a stats object being present in the processed metrics
(spoiler: it isn't present in the processed metrics).
Solution:
Use a better check for no traffic.
The new check checks for both no requests (so nil request rate) and
also no latency (in the case that the service is http but receiving no traffic).

Adds local and cloud integration testing for the dashboard using WebdriverIO and
SauceLabs. Includes documentation on how to set up and run the Sauce Connect

Note: for web development, the web server launched by `bin/web run` and `bin/web
dev` is now 7777, not 8084, because the Sauce Connect proxy can only tunnel to

When installing Linkerd, a user may override default settings, or may
explicitly configure defaults. Consider install options like `--ha
--controller-replicas=4` -- the `--ha` flag sets a new default value for
the controller-replicas, and then we override it.
When we later upgrade this cluster, how can we know how to configure the
cluster?
We could store EnableHA and ControllerReplicas configurations in the
config, but what if, in a later upgrade, the default value changes? How
can we know whether the user specified an override or just used the
default?
To solve this, we add an `Install` message into a new config.
This message includes (at least) the CLI flags used to invoke
install.
upgrade does not specify defaults for install/proxy-options fields and,
instead, uses the persisted install flags to populate default values,
before applying overrides from the upgrade invocation.
This change breaks the protobuf compatibility by altering the
`installation_uuid` field introduced in 9c442f6885.
Because this change was not yet released (even in an edge release), we
feel that it is safe to break.

When a resource only has TCP traffic and no HTTP traffic, the dashboard looks
weird in a bunch of places.
This branch:
- updates the main resource card in the Octopus graph to show TCP stats if no HTTP
stats are available
- cleans up the resource detail page to show fewer blank
tables if the resource only has TCP traffic.
This change introduces a new Identity service implementation for the
`io.linkerd.proxy.identity.Identity` gRPC service.
The `pkg/identity` contains a core, abstract implementation of the service
(generic over both the CA and (Kubernetes) Validator interfaces).
`controller/identity` includes a concrete implementation that uses the
Kubernetes TokenReview API to validate serviceaccount tokens when
issuing certificates.
This change does **NOT** alter installation or runtime to include the
identity service. This will be included in a follow-up.
The proxy's TLS implementation has changed to use a new _Identity_ controller.
In preparation for this, the `--tls=optional` CLI flag has been removed
from install and inject; and the `ca` controller has been deleted. Metrics
and UI treatments for TLS have **not** been removed, as they will continue to
be valuable for the new Identity system.
With the removal of the old identity scheme, the Destination service's proxy
ID field is now set with an opaque string (e.g. `ns:emojivoto`) to enable
locality awareness.
Fixes#2420.

This PR creates a "Community" menu item on the dashboard sidebar that, when clicked, displays an iFrame of a page on linkerd.io.

This is calculated by comparing a date in the user's localStorage to a JSON feed at linkerd.io.
linkerd/linkerd2#1721 introduced a `--single-namespace` install flag,
enabling the control-plane to function within a single namespace. With
the introduction of ServiceProfiles, and upcoming identity changes, this
single namespace mode of operation is becoming less viable.
This change removes the `--single-namespace` install flag, and all
underlying support. The control-plane must have cluster-wide access to
operate.
A few related changes:
- Remove `--single-namespace` from `linkerd check`, this motivates
combining some check categories, as we can always assume cluster-wide
requirements.
- Simplify the `k8s.ResourceAuthz` API, as callers no longer need to
make a decision based on cluster-wide vs. namespace-wide access.
Components either have access, or they error out.
- Modify the web dashboard to always assume ServiceProfiles are enabled.

Some time ago, I fixed sorting on these tables so that the default route ([default])

to no longer put the default route at the bottom. Update to correct case.
linkerd/linkerd2#2428 modified SelfSubjectAccessReview behavior to no
longer paper-over failed ServiceProfile checks, assuming that
ServiceProfiles will be required going forward. There was a lingering
ServiceProfile check in the web's startup that started failing due to
this change, as the web component does not have (and should not need)
ServiceProfile access. The check was originally implemented to inform
the web component whether to expect "single namespace" mode or
ServiceProfile support.

This PR adds filter functionality to the web UI via an optional Material-UI <Toolbar> on the top of the table which contains the table's title and a filter icon. The toolbar only shows if the enableFilter={true} prop is passed down from the parent component. The PR modifies the MetricsTable test and adds tests for BaseTable and TopRoutesTable.
Note: The previous Ant-based UI allowed certain tables to be filtered by individual table column; this capacity is not part of this PR but can be added later if useful.
The control-plane components relied on a `--single-namespace` param,
passed from `linkerd install` into each individual component, to
determine which namespaces they were authorized to access, and whether
to support ServiceProfiles. This command-line flag was redundant given
the authorization rules encoded in the parent `linkerd install` output,
via [Cluster]Role[Binding]s.
Modify the control-plane components to query Kubernetes at startup to
determine which namespaces they are authorized to access, and whether
ServiceProfile support is available. This allows removal of the
`--single-namespace` flag on the components.

In #2195 we introduced `linkerd endpoints` on the CLI. I would like similar

This PR adds an api endpoint at `/api/endpoints`, and introduces a new debugging

Up until now, the proxy-api controller service has been the sole service
that the proxy communicates with, implementing the majoriry of the API
defined in the `linkerd2-proxy-api` repo. But this is about to change:
linkerd/linkerd2-proxy-api#25 introduces a new Identity service; and
this service must be served outside of the existing proxy-api service
in the linkerd-controller deployment (so that it may run under a
distinct service account).
With this change, the "proxy-api" name becomes less descriptive. It's no
longer "the service that serves the API for the proxy," it's "the
service that serves the Destination API to the proxy." Therefore, it
seems best to bite the bullet and rename this to be the "destination"
service (i.e. because it only serves the
`io.linkerd.proxy.destination.Destination` service).

When Kubernetes periodically pinged booksapp to perform a health check, the

unnecessary queryString construction.

@rmars and I set out to replace all instances of lodash filter with native
filter in order to prevent the additional import. However, there was only one
use of _filter that could be easily replaced, since our other uses depend on
lodash's ability to handle empty variables, and the ability to filter both
objects and arrays (JS's native filter is only for arrays). Switching to native
filter in those cases would have required us to manually check the value of the
variable, set it to an empty array and/or convert it from an object to an array.

When looking up service profiles, Linkerd always looks for the service profile objects in the Linkerd control namespace. This is limiting because service owners who wish to create service profiles may not have write access to the Linkerd control namespace.
Instead, we have the control plane look for the service profile in both the client namespace (as read from the proxy's `proxy_id` field from the GetProfiles request and from the service's namespace. If a service profile exists in both namespaces, the client namespace takes priority. In this way, clients may override the behavior dictated by the service.

# Problem
In order to switch Linkerd template rendering to use `.yaml` files, static
assets must be bundled in the Go binary for use by `linkerd install`.
# Solution
The solution should not affect the local development process of building and
testing.
[vfsgen](https://github.com/shurcooL/vfsgen) generates Go code that statically
implements the provided `http.FileSystem`. Paired with `go generate` and Go
[build tags](https://golang.org/pkg/go/build/), we can continue to use the
template files on disk when developing with no change required.
In `!prod` Go builds, the `cli/static/templates.go` file provides a
`http.FileSystem` to the local templates. In `prod` Go builds, `go generate
./cli` generates `cli/static/generated_templates.gogen.go` that statically
provides the template files.
When built with `-tags prod`, the executable will be built with the staticlly
generated file instead of the local files.
# Validation
The binaries were compiled locally with `bin/docker-build`. The binaries were
then tested with `bin/test-run (pwd)/target/cli/darwin/linkerd`. All tests
passed.

# Problem
In order to refactor `install` to allow for a more flexible configuration, we
should start with the format of the YAML that it renders. Using the Helm
YAML format will make it easier add flexible configuration options in the
future. Currently, the rendered template that `install` produces does not
follow this format.
# Solution
Use the internals that Helm itself uses to render an inject template that
follows the same formatting rules. Helm's `template` cmd provides a good
outline of what is needed to make Linkerd's `install` cmd work as if it was
a Chart.
# Validation
There are no new tests, but there may not be anything to test at this stage.
This is a WIP PR towards the ultimate goal of `install` allowing a more
flexible configuration.
However, `install` now uses all the Helm `template` internals and therefore
satisfies the needed properties for Helm Charts.

[web UI] Previously, we were specifying the display order to display the cli flags in the

- adds dropdown with populated options for service / namespace
As part of this work, made TapQueryCliCmd more generic, so it can work
for other CLI commands besides tap/top.
Adds a (currently not displayed in sidebar, but available at /routes) page to
mirror the current functionality of `linkerd routes <service>`. So far, this is just a
barebones form and table, but it works.
Adds a /api/routes path and handler to the api to receive TopRoutes requests from the web.
Add a barebones ListServices endpoint, in support of autocomplete for services.
As we develop service profiles, this endpoint could probably be used to describe
more aspects of services (like, if there were some way to check whether a
service profile was enabled or not).
Accessible from the web UI via http://localhost:8084/api/services
Add a routes command which displays per-route stats for services that have service profiles defined.
This change has three parts:
* A new public-api RPC called `TopRoutes` which serves per-route stat data about a service
* An implementation of TopRoutes in the public-api service. This implementation reads per-route data from Prometheus. This is very similar to how the StatSummaries RPC and much of the code was able to be refactored and shared.
* A new CLI command called `routes` which displays the per-route data in a tabular or json format. This is very similar to the `stat` command and much of the code was able to be refactored and shared.
Note that as of the currently targeted proxy version, only outbound route stats are supported so the `--from` flag must be included in order to see data. This restriction will be lifted in an upcoming change once we add support for inbound route stats as well.

Try to squish the metrics columns so that the data fits on the page without

A container called `proxy-api` runs in the Linkerd2 controller pod. This container listens on port 8086 and serves the proxy-api but does nothing other than forward gRPC requests to the destination container which listens on port 8089.
We remove the proxy-api container altogether and change the destination container to listen on port 8086 instead of 8089. The result is that clients still use the proxy-api by connecting to `proxy-api.<ns>.svc.cluster.local:8086` but the controller has one fewer containers. This results in a simpler system that is easier to reason about.

* Move proxy-injector to its own deployment
* Ignore pods that already have proxy injected
This ensures the webhook doesn't error out due to proxy that are injected using the command
* PR review items on creating/updating the MWC on-start
* Replace API calls to ConfigMap with file reads
* Fixed post-rebase broken tests
* Don't mutate the auto-inject label
Since we started using healhcheck.HasExistingSidecars() to ensure pods with
existing proxies aren't mutated, we don't need to use the auto-inject label as
an indicator.
This resolves a bug which happens with the kubectl run command where the deployment

label to not match the deployment label, causing kubectl run to fail.

Use the same tap data we use to display the unmeshed resources in the Octopus

The unmeshed rows are filtered by resource type, so if we're on a Deployments

as IPs, will still show in the octopus graph).
* Use the list of unmeshed resources to display unmeshed sources in the table
* Keep track of number of pods in unmeshed sources
When I deleted a resource, I noticed that hard refreshing the page resulted in
js errors that would break the UI (e.g. if you were on a pod page, and the pod's
deployment was deleted, the pod would no longer be found, and the page would
error). This PR better handles not-present resources so that the UI still shows
up and shows you that there aren't metrics for that resource.

Draw customizable SVG paths for octopus arms.
This also combines all the unmeshed resources into a list and displays them in
one resource box, instead of adding one box per unmeshed resource. This helps
keep the box heights constant, which I want to draw the arrows.
When a resource has no tap events being streamed to the Tap UI, and a user hits the "Stop" button in the Tap page, the tap stream is left open due to the WebSocket connection not being closed.
It looks like the web server's tap client that is created to stream events from the tap server blocks the main request thread in the web server. This causes the web server to stop receiving any subsequent close frames from the UI i.e. when the "Stop" button is clicked.
This PR moves the tapClient initialization code to a separate goroutine, specifically, the goroutine that reads tap events from the incoming grpc tap stream. This allows the main thread to continue reading messages from the WebSocket connection and allow it to receive close frames.

If you go to /top and select a namespace and then a resource, and then clear the
resource, there would be a javascript error that would cause the whole app not
to render. Fix this.
Problem
Previously, we'd display one row in top per sourcePod -> dstPod. When
viewing resources at a higher level though (e.g. deployments with multiple pods)
the src/dst column displays the resource at that level, and displaying multiple
rows with deploy/foo is confusing.
Solution
Key the top table off of the resource currently being requested, so
that all the rows are rolled up appropriately. In the popover for that column,
display a list of pods/ips that are rolled up.
This branch also adds a generic list of resources to the tap/top dropdown (you
were always able to tap them, but when I switched from autocomplete to select
for this dropdown, you lost the ability to type in arbitrary resources).
If you select a from namespace and from resource in /tap and try to clear them
using the little x in the form field, there would be a huge js error causing the
app to not render. Fix this.
Also removes filterOptions which wasn't being used any more. This will probably
make parsing tap results ever so slightly faster as we're now not trying to also
aggregate potential filter options.
* Fix js errors on Tap form when Clear button is hit
* Remove filter options code since we're not using the filters anywhere
When a websocket connection is closed between Chrome and a server, we get a 1006 error code signifying abnormal closure of the websocket connection. It seems as if we only get this error on Chrome web clients. Firefox and Safari do not encounter this issue.
The solution is to suppress 1006 errors that occur in the web browser since the connection is closed anyway. There is no negative side effect that occurs when the connection is closed abnormally and so the error message is benign.

There are two variables we use to control the volume of Top output,
maxRowsToDisplay, which controls how many rows are in the table, and
maxRowsToStore, which controls the size of the event index we keep in memory for
aggregating results.
Previously, we were only keeping in index maxRowsToDisplay rows, which for the
Resource Detail page was 10 (which is really small for high traffic rest-y
resource traffic - it causes rows to be deleted from the index too soon, and
then causes the data in the table to change a lot). Change this to store
maxRowsToStore rows, and also bump this to 50. This allows us to store results
for longer, and also ensures more consistent data over time.
Another fix for the appearance of the Top columns is to add fixed widths to the
metrics. This will prevent the table from wobbling from side to side.
A bunch of web UI tweaks:
- Add a small success rate chart to the metrics tables
- Improve latency formatting for seconds latencies
- Rename upstream/downstream to inbound/outbound

* Use Tap data on Resource Detail page to display unmeshed resources

* Don't update neighbors on every websocket recv; this causes too much rendering.
Instead, store in internal variable and update with the api results.
This branch uses the src data from tap to discern which unmeshed resources are
sending traffic to the specified resource. We then show this resource in the
octopus graph.
Note that tap is sampled data, so it's possible for an unmeshed resource to not
show up. Also, because we won't know about the resource until it appears in the
Tap results, results could pop into the chart at any time.
_.throttle setState for receiving websocket tap events to prevent continuous rerendering
Problem
We receive a lot of websocket events from the tap server. Previously, we
were processing each event as we received it, then calling setState after
processing to update the tables. Each call to setState triggered a re-render of
the whole table. We were rerendering multiplie times a second, causing the whole
page to become unresponsive.
Solution
Throttle setState for receiving websocket tap events to prevent
continuous rerendering. Store the tap events in an index outside of state, and
only update the state once every specified interval (currently 500ms).
We can now view entire namespaces with Top and the page won't crash!
To verify: Go to /top and try topping a namespace

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.
