Minimum 16 GB RAM additional memory is strongly recommended, especially if etcd is co-located on masters. Consult Hardware Recommendations to properly size your etcd nodes. Currently, OpenShift Container Platform stores image, build, and deployment metadata in etcd.

You must periodically prune old resources. If you are planning to leverage a large number of these resources, place etcd on machines with large amounts of memory and fast SSD drives.

See Managing Storage with Docker-formatted Containers for instructions on configuring this during or after installation. Test or sample environments function with the minimum requirements.

Installing

For production environments, the following recommendations apply:. In a highly available OpenShift Container Platform cluster with external etcd, a master host should have, in addition to the minimum requirements in the table above, 1 CPU core and 1.

However, in smaller clusters of less than pods, this cache can waste a lot of memory for negligible CPU load reduction. The default cache size is 50, entries, which, depending on the size of your resources, can grow to occupy 1 to 2 GB of memory.

The size of a node host depends on the expected size of its workload. As an OpenShift Container Platform cluster administrator, you will need to calculate the expected workload, then add about 10 percent for overhead. For production environments, allocate enough resources so that a node host failure does not affect your maximum capacity.

Oversubscribing the physical resources on a node affects resource guarantees the Kubernetes scheduler makes during pod placement. Learn what measures you can take to avoid memory swapping. Used for etcd storage only when in single master mode and etcd is embedded in the atomic-openshift-master process.

Used for etcd storage when in Multi-Master mode or when etcd is made standalone by an administrator. When the run time is docker, this is the mount point. Storage used for active container runtimes including pods and storage of local images not used for registry storage. Mount point should be managed by docker-storage rather than manually.

When the run time is CRI-O, this is the mount point. Additional GB for every additional 8 GB of memory. Ephemeral volume storage for pods. This includes anything external that is mounted into a container at runtime. Includes environment variables, kube secrets, and data volumes not backed by persistent storage PVs.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

This is essentially the same issue as 49 in a different contex. Let me know if you'd prefer to resurrect that discussion instead. Even fixing that specific issue, using something like the below, just results in different permissions problems down the line.

Is there no way to run the elasticsearch container on platforms with runtime user IDs? If you can't use docker volumes see the link abovethe best approach would be to adjust the gid of the elasticsearch on your host for the gid e.

Thanks dliappis! This is the case for the config directory as well. Using OpenShift and some other Kubernetes platforms the user ID is only known at runtime instead of at build time making the Dockerfile approach somewhat difficult. I'll give that a shot, but that can be a bit tricky. You are welcome agc93! For the k8s case we have a similar open issue, After searching a bit, my understanding is that it's now possible to use the securityContext definition in the Pod.

This should be possible after k8s ver 1. You can also use an init container workaround, as shown here. Thanks for the info dliappisand sorry for taking so long closing the loop on this one been out of the country. I've currently got it running successfully using my own image using the following Dockerfile:.

So the issue being hit here is not strictly related to the data directory, and more importantly isn't related to the user who starts the container i. Openshift uses semi-random high UIDs as the actual container user i. Additionally, using scc inside templates gets pretty unwieldy and can break portability.

Thanks for the update agc I'd be interested to hear on which occasions securityContext is not recommended, if you have some links. In our experience most docker images that use a preconfigured user, such as database images, consul etc. Your offer for a PR is highly valued thanks! I have been planning to PR the sudo solution for granting access to bind mounts in my earlier commentthrough a startup option env var.

The recommendation against securityContext I've seen is mostly more a case of "if you use these, it's best to also change the security options". With OpenShift and Kubernetes' new RBAC, which is based on OpenShift'sthe out-of-box security has quite a clear division between privileged and unprivileged and not much middle-ground. To effectively add securityContext to the mix often means adjusting these as well. Huh, good to know! Closed by Hey agc93 the recently released 6.

Description of the problem including expected versus actual behavior : Running Elasticsearch in Openshift doesnt work when specifing a Certificate which was provided by the platform.

It seems the Elasticsearch User is not running as root which is good but not with GUID 0, which is necessary to access those files. Please include a minimal but complete recreation of the problem, including e. The easier you make for us to reproduce it, the more likely that somebody will take the time to look at it. I've checked the docker-entrypoint. Still this seems not to be enough.

Furthermore I am not able to connect to the container in openshift via terminal. I get the following message: Could not connect to the container. Do you have sufficient privileges?

This comment has been minimized. Sign in to view.Edit This Page. A security context defines privilege and access control settings for a Pod or Container.

Security context settings include:. Linux Capabilities : Give a process some privileges, but not all the privileges of the root user. AppArmor : Use program profiles to restrict the capabilities of individual programs.

AllowPrivilegeEscalation: Controls whether a process can gain more privileges than its parent process. You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikubeor you can use one of these Kubernetes playgrounds:. To specify security settings for a Pod, include the securityContext field in the Pod specification.

The securityContext field is a PodSecurityContext object. The security settings that you specify for a Pod apply to all Containers in the Pod.

Here is a configuration file for a Pod that has a securityContext and an emptyDir volume:. In the configuration file, the runAsUser field specifies that for any Containers in the Pod, all processes run with user ID The runAsGroup field specifies the primary group ID of for all processes within any containers of the Pod.

If this field is omitted, the primary group ID of the containers will be root 0. Any files created will also be owned by user and group when runAsGroup is specified. Since fsGroup field is specified, all processes of the container are also part of the supplementary group ID The output shows that the processes are running as userwhich is the value of runAsUser :. The output shows that testfile has group IDwhich is the value of fsGroup.

You will see that gid is which is same as runAsGroup field. If the runAsGroup was omitted the gid would remain as 0 root and the process will be able to interact with files that are owned by root 0 group and that have the required group permissions for root 0 group. For large volumes, checking and changing ownership and permissions can take a lot of time, slowing Pod startup. You can use the fsGroupChangePolicy field inside a securityContext to control the way that Kubernetes checks and manages ownership and permissions for a volume.

This field only applies to volume types that support fsGroup controlled ownership and permissions.

This field has two possible values:. This is an alpha feature. To use it, enable the feature gate ConfigurableFSGroupPolicy for the kube-api-server, the kube-controller-manager, and for the kubelet. To specify security settings for a Container, include the securityContext field in the Container manifest. The securityContext field is a SecurityContext object.

Security settings that you specify for a Container apply only to the individual Container, and they override settings made at the Pod level when there is overlap. Here is the configuration file for a Pod that has one Container.

Both the Pod and the Container have a securityContext field:. The output shows that the processes are running as user This is the value of runAsUser specified for the Container. It overrides the value that is specified for the Pod.

With Linux capabilitiesyou can grant certain privileges to a process without granting all the privileges of the root user.

To add or remove Linux capabilities for a Container, include the capabilities field in the securityContext section of the Container manifest. Here is configuration file that does not add or remove any Container capabilities:.You are viewing documentation for a release that is no longer supported.

The latest supported version of version 3 is 3. For the most recent version 4, see 4. For production environments, several factors influence installation.

Consider the following questions as you read through the documentation:. Both the quick and advanced installation methods are supported for development and production environments. If you want to quickly get OpenShift Container Platform up and running to try out for the first time, use the quick installer and let the interactive CLI guide you through the configuration options relevant to your environment.

This method is particularly suited if you are already familiar with Ansible. However, following along with the OpenShift Container Platform documentation should equip you with enough information to reliably deploy your cluster and continue to manage its configuration post-deployment using the provided Ansible playbooks directly.

If you wanted to later switch to using the advanced method, you can create an inventory file for your configuration and carry on that way.

Determine how many nodes and pods you require for your OpenShift Container Platform cluster. Cluster scalability correlates to the number of pods in a cluster environment. That number influences the other numbers in your setup. Oversubscribing the physical resources on a node affects resource guarantees the Kubernetes scheduler makes during pod placement.

Learn what measures you can take to avoid memory swapping. If you want to scope your cluster for pods per cluster, you would need at least 9 nodes, assuming that there are maximum pods per node:. If you increase the number of nodes to 20, then the pod distribution changes to pods per node:. This section outlines different examples of scenarios for your OpenShift Container Platform environment.

Use these scenarios as a basis for planning your own OpenShift Container Platform cluster, based on your sizing needs. Moving from a single master cluster to multiple masters after installation is not supported. OpenShift Container Platform can be installed on a single system for a development environment only.

An all-in-one environment is not considered a production environment. The following table describes an example environment for a single master with embedded etcd and two nodes :. The following table describes an example environment for a single masterthree etcd hosts, and two nodes :. When specifying multiple etcd hosts, external etcd is installed and configured. The following describes an example environment for three mastersone HAProxy load balancer, three etcd hosts, and two nodes using the native HA method:.

See Installing a Stand-alone Registry for details on this scenario. An RPM installation installs all services through package management and configures services to run within the same user space, while a containerized installation installs services using container images and runs separate services in individual containers. See the Installing on Containerized Hosts topic for more details on configuring your installation to use containerized services.

The following sections identify the hardware specifications and system-level requirements of all hosts within your OpenShift Container Platform environment. If you do not, contact your sales representative for more information. Test or sample environments function with the minimum requirements.

For production environments, the following recommendations apply:. When planning an environment with multiple masters, a minimum of three etcd hosts and a load-balancer between the master hosts are required.

However, in smaller clusters of less than pods, this cache can waste a lot of memory for negligible CPU load reduction.

Back to blog. September 21, by Jim Minter. Looking for newer information on Helm? Check out our guide to making Kubernetes Operators with Helm in 5 steps! Helm needs little introduction as a popular way of defining, installing, and upgrading applications on Kubernetes. This post will walk you through getting both the Tiller server and Helm client up and running on OpenShift, and then installing your first Helm Chart. It assumes that you already have the OpenShift oc client installed locally and that you are logged into your OpenShift instance.

Note that this post is solely an illustration of how OpenShift and Helm can run together; Helm is not a technology supported by Red Hat. If you are looking for a Red Hat supported way to define and install applications, please see OpenShift Templates and Ansible. This provides a clear and beneficial separation between the Tiller server and its data and the application s that it manages. Using the above model, you can install your own private Tiller server on OpenShift to manage one or more applications across one or more of your own projects.

Before we get down to business, a few words of warning. A feature of Helm is that it makes it very easy to download and install arbitrary containerised applications from the internet. However, think twice before using this power!

Could they have security issues that will cause you problems? Will they be updated quickly if a security problem is discovered later? Every image from the Red Hat Container Catalog has a Container Health Indexand clearly shows security advisories and available updates, helping you to stay secure.

To keep your cluster safe by default, OpenShift prevents containers from running as root although cluster-admins can override this. However, the good news is that none of this prevents you from installing and managing secure non-root containers on OpenShift using Helm.
