I need to deploy redis-sentinel with redis-stack modules (redis-search and redis-json) by using docker compose but I can't find any reference. Can someone refer me to a docker compose example or explain how can I deploy it with docker?
If you don't have much experience with docker, but want a relatively "easy" way to setup with compose, you could take a look at Bitnami images.
For Redis Sentinel: bitnami/redis-sentinel.

Trying to configure AWX runtime using Docker with Docker Compose. With image quay.io/ansible/awx:21.7.0 it seems a little tricky. I don't want to set up Kubernetes and use AWX Operator - don't have resources and tasks for this complicity, just redundant tools. All I need - it is running Docker process with some additional services in my infrastructure (for example Traefik and SystemD services, AWX one of them).
Does anyone have moving on this way? Trying to find production Dockerfile (I think it uses in prod, right?) and prepare Django environment to work inside docker-compose (env vars, networks, resources, services).
I'll be updating this post with my results. Thanks guys, I hope I'm not alone with this problem.
I'm having trouble Installing kubeadm on my amazon linux 2 instance specifically when i try to create a cluster,
when i try Installing runtime i get to chose which one to use :
containerd
CRI-O
Docker Engine
Mirantis Container Runtime
first of all i'm wondering which one i should use between them that is compatible with amazon linux 2 and second of all whenever i run yum install for any CRI i get this same error:
this is the output of the command: yum install cri-o
the doc that i followed is: https://kubernetes.io/docs/setup/production-environment/container-runtimes/
hi, hope you are enjoying your kubernetes Journey !
First off, you I wanna tell you that you can use whichever you want between the container runtime you want to install.
You can use docker if you are not familiar with the others but containerd is in my opinion the best lightweight alternative ( containerd is used in docker, but for kubernetes you don't need all the layers that docker provides only the container runtime Itself, here containerd ) you can read this for more info, but there is plenty of documentation about this.: https://www.tutorialworks.com/difference-docker-containerd-runc-crio-oci/
Second of all, I don't know how you are trying to install your kubernetes cluster but again there is few couples of way to do it:
The hardest but very instructive can be kubernetes the hard way ( https://github.com/kelseyhightower/kubernetes-the-hard-way )
Next you can use kubeadm (again there is plenty of documentation on the internet but you can follow one of the kubeadm tutorials: https://devopscube.com/setup-kubernetes-cluster-kubeadm/ )
Here is a list of tools that you can use to install your kubernetes cluster, you can look for tutorials for each of them on the internet: https://dzone.com/articles/50-useful-kubernetes-tools )
Last but not least, since you are on aws, you can use the AWS EKS service to setup quickly a robust kubernetes cluster. (https://aws.amazon.com/fr/eks/)
This is for AWS. If you want a local k8s cluster I strongly suggest you to use kind (kubernetes in docker)
Bguess
I have a single node Kubeadm deployment, I want do be able to run docker images the same way that you can in Minikube with eval $(minikube docker-env), is this possible?
I know that I can side-load a tarball and start a docker image to host my images, but I don't want that. Also, it seems that it would be most helpful to find out how to find the environment variables related to any program, not just this one. I will be looking into that but figured I would ask in case someone knew right away.
For the docker image containing kubeadm binary, you can find it on docker hub here (e.g for Kubernetes v1.14.0 - use 'kindest/node:v1.14.0')
If you want to re-use node's docker-engine, please follow one of many online tutorials on how to 'connect docker client to a remote docker daemon'. e.g this one. If you want to have a similar experience like with 'minikube docker-env', install standalone docker-machine tool, and follow instruction from this guide.
I am new to docker and I have instantiated a strapi container which needs a mongoDB container to be run first. I am currently running this in AWS ECS where I configured the task definition to have both the containers and linked.
I am now just wondering if I can make a docker image out of the existing container system. So in future, I could maybe just post this new image to dockerhub or ECR and run in ECS without any additional configuration like Environment variables or links or multiple containers in single task defintion.
Any ideas would be helpful.
you can create docker image by
docker commit (container-name)
Do I need to install an instance of Spring Cloud Data Flow on the master server myself, or is this getting installed "automatically" as part of the deployment?
This isn't quite clear from the description at
http://docs.spring.io/spring-cloud-dataflow-server-kubernetes/docs/current-SNAPSHOT/reference/htmlsingle/#_deploying_streams_on_kubernetes
I've followed the guide, though removed every config for MySQL. Maybe this is required. Though I'm somewhat stuck since it's just not assigning an external IP and I do not see why, how to debug, and whether I missed to install some required component.
Edit:
To clarify, I see a scdf service entry when I run
kubectl get svc
But this service never gets an external IP.

Spring Cloud Data Flow server needs to be setup either outside (that knows how to connect to the kubernetes environment) or you can use the Spring Cloud Data Flow server docker image to run inside the kubernetes while the latter approach is better.
Step 6 in the link you posted above runs the SCDF docker image inside the kubernetes cluster:
```
Deploy the Spring Cloud Data Flow Server for Kubernetes using the Docker image and the configuration settings you just modified.
$ kubectl create -f src/etc/kubernetes/scdf-config-kafka.yml
$ kubectl create -f src/etc/kubernetes/scdf-secrets.yml
$ kubectl create -f src/etc/kubernetes/scdf-service.yml
$ kubectl create -f src/etc/kubernetes/scdf-controller.yml
```
MySql is required, that's why it's in the steps.
Spring Cloud Data Flow uses an RDBMS instead of Redis for stream/task
definitions, application registration, and for job repositories.
You can also use any of the other supported RDMBSes.
You can install it using Helm Charts.
https://dataflow.spring.io/docs/installation/kubernetes/helm/
At first install Helm
Then install Spring Cloud Data Flow
helm install --name my-release stable/spring-cloud-data-flow
It will install and config relevant pods such as spring-cloud-dataflow-server, mysql, skipper, rabbitmq, etc.
Also you can customize versions and configurations.
