# Migration Guide: From v1 to v2
|
|
|
|
How to Migrate from Traefik v1 to Traefik v2.
|
|
{: .subtitle }
|
|
|
|
The version 2 of Traefik introduces a number of breaking changes,
|
|
which require one to update their configuration when they migrate from v1 to v2.
|
|
The goal of this page is to recapitulate all of these changes, and in particular to give examples,
|
|
feature by feature, of how the configuration looked like in v1, and how it now looks like in v2.
|
|
|
|
!!! info "Migration Helper"
|
|
|
|
We created a tool to help during the migration: [traefik-migration-tool](https://github.com/containous/traefik-migration-tool)
|
|
|
|
This tool allows to:
|
|
|
|
- convert `Ingress` to Traefik `IngressRoute` resources.
|
|
- convert `acme.json` file from v1 to v2 format.
|
|
- migrate the static configuration contained in the file `traefik.toml` to a Traefik v2 file.
|
|
|
|
## Frontends and Backends Are Dead... <br/>... Long Live Routers, Middlewares, and Services
|
|
|
|
During the transition from v1 to v2, a number of internal pieces and components of Traefik were rewritten and reorganized.
|
|
As such, the combination of core notions such as frontends and backends has been replaced with the combination of [routers](../routing/routers/index.md), [services](../routing/services/index.md), and [middlewares](../middlewares/overview.md).
|
|
|
|
Typically, a router replaces a frontend, and a service assumes the role of a backend, with each router referring to a service.
|
|
However, even though a backend was in charge of applying any desired modification on the fly to the incoming request,
|
|
the router defers that responsibility to another component.
|
|
Instead, a dedicated middleware is now defined for each kind of such modification.
|
|
Then any router can refer to an instance of the wanted middleware.
|
|
|
|

## TLS Configuration is Now Dynamic, per Router.
|
|
|
|
TLS parameters used to be specified in the static configuration, as an entryPoint field.
|
|
With Traefik v2, a new dynamic TLS section at the root contains all the desired TLS configurations.
|
|
Then, a [router's TLS field](../routing/routers/index.md#tls) can refer to one of the [TLS configurations](../https/tls.md) defined at the root, hence defining the [TLS configuration](../https/tls.md) for that router.

## HTTP to HTTPS Redirection is Now Configured on Routers
|
|
|
|
Previously on Traefik v1, the redirection was applied on an entry point or on a frontend.
|
|
With Traefik v2 it is applied on a [Router](../routing/routers/index.md).
|
|
|
|
To apply a redirection, one of the redirect middlewares, [RedirectRegex](../middlewares/redirectregex.md) or [RedirectScheme](../middlewares/redirectscheme.md), has to be configured and added to the router middlewares list.

## Strip and Rewrite Path Prefixes
|
|
|
|
With the new core notions of v2 (introduced earlier in the section
|
|
["Frontends and Backends Are Dead... Long Live Routers, Middlewares, and Services"](#frontends-and-backends-are-dead-long-live-routers-middlewares-and-services)),
|
|
transforming the URL path prefix of incoming requests is configured with [middlewares](../middlewares/overview.md),
|
|
after the routing step with [router rule `PathPrefix`](https://docs.traefik.io/v2.0/routing/routers/#rule).
|
|
|
|
Use Case: Incoming requests to `http://company.org/admin` are forwarded to the webapplication "admin",
|
|
with the path `/admin` stripped, e.g. to `http://<IP>:<port>/`. In this case, you must:
|
|
|
|
* First, configure a router named `admin` with a rule matching at least the path prefix with the `PathPrefix` keyword,
|
|
* Then, define a middleware of type [`stripprefix`](../middlewares/stripprefix.md), which removes the prefix `/admin`, associated to the router `admin`.

|

|
??? question "What About Other Path Transformations?"
|
|
|
|
Instead of removing the path prefix with the [`stripprefix` middleware](../../middlewares/stripprefix/), you can also:
|
|
|
|
* Add a path prefix with the [`addprefix` middleware](../../middlewares/addprefix/)
|
|
* Replace the complete path of the request with the [`replacepath` middleware](../../middlewares/replacepath/)
|
|
* ReplaceRewrite path using Regexp with the [`replacepathregex` middleware](../../middlewares/replacepathregex/)
|
|
* And a lot more on the [`middlewares` page](../../middlewares/overview/)

## Traefik Logs
|
|
|
|
In the v2, all the [log configuration](../observability/logs.md) remains in the static part but are unified under a `log` section.
|
|
There is no more log configuration at the root level.

|

|
|
## Tracing
|
|
|
|
Traefik v2 retains OpenTracing support. The `backend` root option from the v1 is gone, you just have to set your [tracing configuration](../observability/tracing/overview.md).
|
|
|
|
!!! example "Simple Jaeger tracing configuration"
|
|
|
|
!!! info "v1"
|
|
|
|

|
|
|
|
## Metrics
|
|
|
|
The v2 retains metrics tools and allows metrics to be configured for the entrypoints and/or services.
|
|
For a basic configuration, the [metrics configuration](../observability/metrics/overview.md) remains the same.
|
|
|
|
!!! example "Simple Prometheus metrics configuration"

|
|
|

|

|
|
entryPoint = "traefik"
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--metrics.prometheus.buckets=[0.1,0.3,1.2,5.0]
|
|

|
|

|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|

|
|

|
|

|
|

|
```
|
|
|
|
## No More Root Level Key/Values
|
|
|
|
To avoid any source of confusion, there are no more configuration at the root level.
|
|
Each root item has been moved to a related section or removed.

## Dashboard
|
|
|
|
You need to activate the API to access the [dashboard](../operations/dashboard.md).
|
|
As the dashboard access is now secured by default you can either:
|
|
|
|
* define a [specific router](../operations/api.md#configuration) with the `api@internal` service and one authentication middleware like the following example
|
|
* or use the [insecure](../operations/api.md#insecure) option of the API
|
|
|
|
!!! info "Dashboard with k8s and dedicated router"
|
|
|
|
As `api@internal` is not a Kubernetes service, you have to use the file provider or the `insecure` API option.

## Some Tips You Should Know
|
|
|
|
* Different sources of static configuration (file, CLI flags, ...) cannot be [mixed](../getting-started/configuration-overview.md#the-static-configuration).
|
|
* Now, configuration elements can be referenced between different providers by using the provider namespace notation: `@<provider>`.
|
|
For instance, a router named `myrouter` in a File Provider can refer to a service named `myservice` defined in Docker Provider with the following notation: `myservice@docker`.
|
|
* Middlewares are applied in the same order as their declaration in router.
|
