[JBoss JIRA] (ISPN-6673) Implement Rolling Upgrades with Kubernetes

by Sebastian Łaskawiec (JIRA)

[ https://issues.jboss.org/browse/ISPN-6673?page=com.atlassian.jira.plugin.... ] Sebastian Łaskawiec updated ISPN-6673: -------------------------------------- Description: There are 2 mechanisms which seems to do the same but are totally different: * [Kubernetes Rolling Update|http://kubernetes.io/docs/user-guide/rolling-updates/] - replaces Pods in controllable fashon * [Infinispan Rolling Updgrate|http://infinispan.org/docs/stable/user_guide/user_guide.html#_Ro...] - a procedure for upgrading Infinispan or changing the configuration Kubernetes Rolling Updates can be used very easily for changing the configuration however if changes are not runtime-compatible, one might loss data. Potential way to avoid this is to use a Cache Store. All other changes must be propagated using Infinispan Rolling Upgrade procedure. was: Currently Kubernetes Rolling Upgrades might damage the cluster and cause data loss. The only way to avoid that is to use a Cache Store. We should instrument the Rolling Upgrades mechanism and indicate when it is safe to scale the cluster in. > Implement Rolling Upgrades with Kubernetes > ------------------------------------------ > > Key: ISPN-6673 > URL: https://issues.jboss.org/browse/ISPN-6673 > Project: Infinispan > Issue Type: Feature Request > Components: Cloud Integrations > Reporter: Sebastian Łaskawiec > Assignee: Sebastian Łaskawiec > > There are 2 mechanisms which seems to do the same but are totally different: > * [Kubernetes Rolling Update|http://kubernetes.io/docs/user-guide/rolling-updates/] - replaces Pods in controllable fashon > * [Infinispan Rolling Updgrate|http://infinispan.org/docs/stable/user_guide/user_guide.html#_Ro...] - a procedure for upgrading Infinispan or changing the configuration > Kubernetes Rolling Updates can be used very easily for changing the configuration however if changes are not runtime-compatible, one might loss data.

[JBoss JIRA] (ISPN-6675) Better configuration management for Kubernetes

by Sebastian Łaskawiec (JIRA)

[ https://issues.jboss.org/browse/ISPN-6675?page=com.atlassian.jira.plugin.... ] Sebastian Łaskawiec commented on ISPN-6675: ------------------------------------------- Creating a new ConfigMap will not propagate updates to the existing Pods (mainly because right now (Kubernetes 1.3) Config Map is not versioned). It also won't trigger redeployment. Those things need to be done manually (using Kubernetes Rolling Updates for example). > Better configuration management for Kubernetes > ---------------------------------------------- > > Key: ISPN-6675 > URL: https://issues.jboss.org/browse/ISPN-6675 > Project: Infinispan > Issue Type: Feature Request > Components: Cloud Integrations > Reporter: Sebastian Łaskawiec > Assignee: Sebastian Łaskawiec > > Currently we either store the configuration in the Docker Image or use system properties to turn the things on/off. Both approaches do not scale. > There are some other alternatives like [Kubernetes ConfigMap|http://kubernetes.io/docs/user-guide/configmap] which are worth exploring -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-6489) Create (or adjust) autoscaling policies in Openshift

by Sebastian Łaskawiec (JIRA)

[ https://issues.jboss.org/browse/ISPN-6489?page=com.atlassian.jira.plugin.... ] Sebastian Łaskawiec commented on ISPN-6489: ------------------------------------------- [Kubernetes built-in Autoscaler|http://kubernetes.io/docs/user-guide/horizontal-pod-autoscaling] supports setting min/max number of instances. Setting properly the minimum value is the key for having a healthy cluster. A suggested way to do it is to let Infinispan calculate the minimum topology and invoke Kubernetes API from inside of the Pod (Kubernetes mounts TOKEN for invoking the API in {{/var/run/secrets}}). > Create (or adjust) autoscaling policies in Openshift > ---------------------------------------------------- > > Key: ISPN-6489 > URL: https://issues.jboss.org/browse/ISPN-6489 > Project: Infinispan > Issue Type: Feature Request > Components: Cloud Integrations > Reporter: Sebastian Łaskawiec > Assignee: Sebastian Łaskawiec > > During the conference [Ray|https://twitter.com/saturnism] mentioned that it would be really nice to have Openshift autoscaling policies for Infinispan based on: > * number of entries (and/or) > * memory usage > Some examples might be found in his repos -- This message was sent by Atlassian JIRA (v6.4.11#64026)
