I installed confluent community platform Manual Install using Systemd on Ubuntu and Debian
I can start:
sudo systemctl start confluent-zookeeper
sudo systemctl start confluent-kafka
...
but where is my confluent path?
I do not have confluent cli
please help
I encountered same problem when setting up elastisearch for confluent. In my system /usr/bin acted as /bin and remaining set up was successfull . So try using /usr as path to confluent if following Manual Install using Systemd on Ubuntu and Debian.
You can manually install Confluent CLI:
curl -L https://cnfl.io/cli | sh -s -- -b /<path-to-directory>/bin
Run this script to install the Confluent CLI. This command creates a
bin directory in your designated location (<path-to-directory>/bin).
The location must be in your PATH (e.g. /usr/local/bin).

How to start hazelcast when try configuring on redhat linux systemctl status hazelcast.service i found error cannot find main class and cannot find any documentation please help. Thank you
From your comment it's obvious you want to run the old Hazelcast IMDG version 3.12.12. This version is not supported by native package managers (as the 5.1 is).
Still, you can install this old Hazelcast as a standalone app and configure the systemd service on your own. See this example repository: https://github.com/kwart/hazelcast-linux-service/tree/3.12.z/
These would be the steps on RHEL (run them as root):
# Prerequisities
dnf install -y wget curl unzip git rsync java-1.8.0-openjdk-headless
# Clone the repo (with 3.12.z branch)
git clone -b 3.12.z https://github.com/kwart/hazelcast-linux-service.git
cd hazelcast-linux-service
# Create the hazelcast user/group
groupadd -r hazelcast
useradd -r -g hazelcast -d /opt/hazelcast -s /sbin/nologin hazelcast
# Install Hazelcast
HAZELCAST_VERSION=3.12.12
wget https://github.com/hazelcast/hazelcast/releases/download/v$HAZELCAST_VERSION/hazelcast-$HAZELCAST_VERSION.zip
unzip hazelcast-$HAZELCAST_VERSION.zip -d /opt
ln -s /opt/hazelcast-$HAZELCAST_VERSION /opt/hazelcast
# Change owner of the Hazelcast directories and links
chown -R hazelcast:hazelcast /opt/hazelcast /opt/hazelcast-$HAZELCAST_VERSION
# Copy service and config files
rsync -r etc/ /etc
# Start and enable service
systemctl daemon-reload
systemctl start hazelcast.service
systemctl enable hazelcast.service
Warning: Hazelcast 3.12.z already reached the end of the standard support. It's highly recommended to use an up-to-date version.
I just installed Minikube for my Kubernetes local setup on Ubuntu 18.04 using the following command:
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
sudo dpkg -i minikube_latest_amd64.deb
However, when I run the command:
minikube start
I get the following error:
bash: /usr/local/bin/minikube: No such file or directory
I'm really wondering what the issue will be.
I just figured it out after some research and trial.
Here's how I fixed it:
I simply closed that terminal and opened a new one, and ran the command again:
minikube start
OR
minikube start --driver=virtualbox
And it worked fine.
Note: By default minikube attempts to use Docker as the driver, but you specify VirtualBox as your preferred driver, which has some advantages.
Another way would have been to reload the Ubuntu bash terminal:
bash --login
Note:
If all the above techniques do not work, you add the Minikube executable to your path:
sudo mv minikube /usr/local/bin
You can then verify the Minikube executable path:
which minikube.
That's all.
I hope this helps
I have started Confluent Platform on my windows 10 using docker with the help of https://docs.confluent.io/current/quickstart/ce-docker-quickstart.html. Now I want to try using Confluent CLI. But I don't see any documentation on how to use confluent cli on docker. Can you please suggest me how can I do this !
Confluent does not provide a docker image for the CLIs at this time (that I'm aware of). Until that time, you could build a simple image locally to package up the CLI for experimenting w/ the command.
Create Dockerfile:
FROM ubuntu:latest
RUN apt update && apt upgrade
RUN apt install -y curl
RUN curl -L --http1.1 https://cnfl.io/cli | sh -s -- -b /usr/local/bin
Then build with:
docker build -t confluent-cli:latest .
Then run on the cp-all-in-one network with:
$ docker run -it --rm --network="cp-all-in-one_default" confluent-cli:latest bash
Then from the containers shell, experiement w/ the command:
root#421e53d4a04a:/# confluent
Manage your Confluent Platform.
Usage:
confluent [command]
Available Commands:
cluster Retrieve metadata about Confluent clusters.
completion Print shell completion code.
help Help about any command
iam Manage RBAC, ACL and IAM permissions.
local Manage a local Confluent Platform development environment.
login Log in to Confluent Platform (required for RBAC).
logout Logout of Confluent Platform.
secret Manage secrets for Confluent Platform.
update Update the confluent CLI.
version Print the confluent CLI version.
Flags:
-h, --help help for confluent
-v, --verbose count Increase verbosity (-v for warn, -vv for info, -vvv for debug, -vvvv for trace).
--version version for confluent
Use "confluent [command] --help" for more information about a command.
Here is the image:
https://hub.docker.com/r/confluentinc/confluent-cli
Basically run the following commands:
devbox1#devbox1:~/onibex/wa$ docker pull confluentinc/confluent-cli
devbox1#devbox1:~/onibex/wa$ docker run confluentinc/confluent-cli
To check if the image was added:
devbox1#devbox1:~/onibex/wa$ docker ps -a | grep confluent-cli
a5ecf9223d35 confluentinc/confluent-cli
Add "sudo" if it is needed.
I am trying to start Confluent 5.3.0 on Ubuntu and need some help.
The first thing I tried was navigating to confluent-5.3.0/bin and running sudo ./confluent start (because that's the way I've been starting Confluent 5.2.1).
This gave an error message: sudo: ./confluent: command not found.
I then checked the folder confluent-5.3.0/bin and found it's missing a shell script named confluent, which is included in 5.2.1.
I checked the Release Notes and the Quickstart. Both of them say I should start Confluent with confluent local start instead of confluent start. (See screenshot at bottom). However, I still get the same error message because the shell script is still missing: sudo: ./confluent: command not found
For those of you who are able to start Confluent 5.3.0, how are you doing it? Can you paste your command line here?
Did you have to write your own confluent shell script for 5.3.0?
Can I just copy my confluent shell script from 5.2.1? I'm assuming it must be incompatible, since they removed it from 5.3.0.
From 5.3.0 you will have to install CLI separately
https://docs.confluent.io/current/cli/installing.html#cli-install
curl -L https://cnfl.io/cli | sh -s -- -b /path-to-directory/bin
Then you can run
confluent local start --path <path-to-directory>
I am trying to install Kubernetes locally on my CentOS. I am following this blog http://containertutorials.com/get_started_kubernetes/index.html, with appropriate changes to match CentOS and latest Kubernetes version.
./kube-up.sh script runs and exists with no errors and I don't see the server started on port 8080. Is there a way to know what was the error and if there is any other procedure to follow on CentOS 6.3
The easiest way to install the kubernetes cluster is using kubeadm. The initial post which details the steps of setup is here. And the detailed documentation for the kubeadm can be found here. With this you will get the latest released kubernetes.
If you really want to use the script to bring up the cluster, I did following:
Install the required packages
yum install -y git docker etcd
Start docker process
systemctl enable --now docker
Install golang
Latest go version because default centos golang is old and for kubernetes to compile we need at least go1.7
curl -O https://storage.googleapis.com/golang/go1.8.1.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.8.1.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
Setup GOPATH
export GOPATH=~/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
Download k8s source and other golang dependencies
Note: this might take sometime depending on your internet speed
go get -d k8s.io/kubernetes
go get -u github.com/cloudflare/cfssl/cmd/...
Start cluster
cd $GOPATH/src/k8s.io/kubernetes
./hack/local-up-cluster.sh
In new terminal
alias kubectl=$GOPATH/src/k8s.io/kubernetes/cluster/kubectl.sh
kubectl get nodes
