Openshift docker x509 certificate signed by unknown authority

The auto-generated and -managed internal CAs will still remain, but only to protect inter-cluster communication. The user-provided certificate can be used with all listeners that have TLS encryption enabled, such as the route, load balancer, ingress, and NodePort types. In this complete example, we will enable an external route listener for one-way TLS authentication.

The first step is to log in as cluster-admin and create a new project.
To be able to download images from the Red Hat Container Registrywe also need to add an authentication Secret use your credentials here :. Then, unzip the installation and examples distribution package with the name ending in -install-examples.
Here we create a small test cluster with a topic just for the sake of this example this cluster is not suitable for production :.
As we will see, if you are not using a self-signed certificate, then you can provide a certificate that includes the whole chain of trust e. The most important point to remember here is that your custom certificate must include the correct Subject Alternative Names SANs. This means having one entry for the bootstrap route and one entry for each broker.
Finally, we just need to configure the external listener by editing the cluster definition and waiting for the rolling update to complete:. Clients only need to trust the root CA public key, regardless of the depth of the chain of trust:.

If you update a Kafka listener certificate in a Secret that is already used by a TLS or external listener, a cluster rolling update is also started. Blog Articles. Everything you need to grow your career.Build, deploy and manage your applications across cloud- and on-premise infrastructure.

For example, by pruning images you can delete older images and layers that are no longer in use, but are still taking up disk space. In order to prune deployments that are no longer required by the system due to age and status, administrators can run the following command:.
Prune all deployments that no longer have a DeploymentConfig, has status is Complete or Failedand has a replica count of zero. Per DeploymentConfig, keep the last N deployments that have a status of Complete and replica count of zero. Per DeploymentConfig, keep the last N deployments that have a status of Failed and replica count of zero. In order to prune builds that are no longer required by the system due to age and status, administrators can run the following command:.
Prune all builds whose Build Configuration no longer exists, status is complete, failed, error, or canceled. Per Build Configuration, keep the last N builds whose status is complete default 5. Per Build Configuration, keep the last N builds whose status is failed, error, or canceled default 1. In order to prune images that are no longer required by the system due to age, status, or exceed limits, administrators can run the following command:.
Currently, to prune images you must first log in to the CLI as a user with an access token. The user must also have the cluster role system:image-pruner or greater for example, cluster-admin. For this operation to work properly, the registry must be configured with storage:delete:enabled set to true.

Pruning images with the --namespace flag does not remove images, only image streams. Images are non-namespaced resources. Therefore, limiting pruning to a particular namespace makes it impossible to calculate their current usage.
By default, the integrated registry caches blobs metadata to reduce the number of requests to storage, and increase the speed of processing the request.
Pruning does not update the integrated registry cache. Images pushed after pruning that contain pruned layers will be broken, because the pruned layers that have metadata in the cache will not be pushed.
Therefore it is necessary to clear the cache after pruning. This can be accomplished by redeploying the registry:. Registry routes are not created by default. See Image Registry Operator in OpenShift Container Platform for information on how to create a registry route and see Exposing the registry for details on how to expose the registry service.

When I use a browser to go to the route of the registry I can see the certificate info and everything looks ok. However, when I try to pull from the registry remotely I get an error saying the "certificate is signed by unknown authority".
I added the key and certificate to my route definition correctly for edge termination. Do I need to do something else? Does the certificate have to be installed somehow in Openshift's config directory? How are you doing that pull? Is this from a command-line, from a node during a pod container image pullor something else? Actually I do not even get to the pull. On the local machine I am able to login. On any remote machine when I run: "docker login -u myopenshiftuser -e peterson. Do you see differences in the cert chain when connecting from the local machine, vs the remote machine:.
It is the same on both machines but the certificate is not right at all. When I go to the registry url I can see the cert and everything looks ok. When I run the openssl command you just gave me, the certification chain looks completely wrong.
I thought by default that uses I use the browser on a remote machine. I get the same strange output from the openssl command on both the remote machine and local machine.
Does that have something to do with the Openssl command failing but the browser showing the certificate ok? I am still stuck on why I am getting the unsigned certificate error just trying to log into the registry on a remote machine. Any non-SNI traffic received on port is handled with TLS termination and a default certificate, which may not match the requested host name, resulting in validation errors.
So when I attempt to communicate with the tls route I set up for the registry with docker login or openssl, it doesn't use the route's ssl configuration and instead uses the generic default openshift ssl certificate? Good catch about SNI. To test that with openssl, add "-servername registry. Not just browsers support SNI, many most? TLS implementations do now c. I would expect everything but the Root CA to be sent by the server. Do you need to include one more intermediate in the certificate provided to the route?
When you did update-ca-trust locally, you may have picked up the additional intermediate cert locally, which is why it can verify but remote machines cannot. Yes, that was it.
I had to use the caCertificate part correctly.
I did try adding that once but I entered the information incorrectly. I have a. I entered that into the route's caCertificate exactly the way it appears in the. Skip to content.

If you're using one of our imagestreams, it should be pointing to a registry that has a trusted certificate. You can mount the certificates using a configuration map or secret.
You must include the new certificates and replace the system certificates in your secret or configuration map that you mount. Is that an untrusted registry?Creating an x client certificate with user role information.

After that, to sign our request we will generate a self-signed CA key and certificate. X certificates can be generated using the openssl command. Generate X. Description The server's X. We will generate a key named t1. You can rate examples to help us improve the quality of examples.
In our case, we'll be generating two client keys branch1 and branch2 and a server key central. This tool creates self-signed certificates that can be used in this test environment.
This is the first post in this series which I will show you how to generate SSL certificate in Java programmatically. In general, we create X certificate using MakeCert. Featuring support for multiple subject alternative names, multiple common names, x v3 extensions, RSA and elliptic curve cryptography. In order to create a CSR, it is first necessary to create a private key. Once you saved the file with the above extension, right click on the file and choose 'Install certificate'.
Copy the certificate file and CA trust file to your Linux system. Certificates can contain or bit RSA keys. This tool has a nice feature where you can paste a hash you have obtained from somewhere and see if it matches any of the computed hashes for the file.
