问题 I've deployed a nodejs and react app to AWS EC2 following this tutorial. I can see the static html title but react views are not rendering. Looking at the network tab I notice some 404 for the get request but I'm not sure where the issue is. Here is my nginx setup: server { listen 80; location / { proxy_pass http://{{my ec2 ip}}:{{5000}}; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http

问题 I am trying to run the command ansible -m ping all from one EC2 instance to another ect2 instance using a different user name than ubuntu.

问题 Is it possible to add aws ec2 nodes to GKE cluster as worker nodes? I created a cluster( named as "mycluster" ) in GKE with the three nodes, now i want to add aws ec2 instance to mycluster as a worker node. Is that possible to add to the existing cluster? please help me on this issue. 回答1: It might be technically possible (if you figured out how to give a kubelet on the AWS node credentials to join the cluster) but it isn't really a great idea for a couple of reasons: Kubernetes is designed

问题 anyone know how to synchronously call AWS Lambda when my new AMI is available? I'd like emphasize that I'm interested in AMI's available state, not just pending. Basically I'm looking for something like RDS Event for EC2. Flow: CreateAMIAPICall --> AMI ami-abc123 is beeing created (pending) --> AMI ami-abc123 is available --> ? --> TRIGGER AWS LAMBDA 回答1: You did not state the language you are using in Lambda, but boto3 has the capability! From EC2 — Boto 3 Docs: waiter = client.get_waiter(

问题 I'm newbie in DB2 database administration and I couldn't think that I'd be stuck with the installation process. I read some documents before installation and found an interesting "db2prereqcheck" thing. So I tried to run it before installation and got an error: DBT3505E The db2prereqcheck utility was unable to determine the Linux distribution level. About this error from ibm: IBM Knowledge Center: DBT3505E IBM Support: db2prereqcheck fails checking Linux distribution I found some other

问题 I am trying to run a bash script through the user_data argument of the spot_fleet_request method. The script executes all the installations and connects to the filesystem, but when it runs the python file I need to run it gives me the following error: Traceback (most recent call last): File "/home/ec2-user/efs/dir/create_lvl_output.py", line 8, in <module> from modeling import generators ImportError: No module named modeling Where modeling is a folder with a script I am importing "modeling

问题 I have multiple instances of EC2 running for a same microservice, which has a Kinesis consumer running(with KCL). My question is, when Kinesis stream gets a new event, since all consumers are polling, will the same event be consumed by consumers of all instances? 回答1: The event will be consumed only by one consumer 回答2: KCL is designed so that each shard is processed by only one worker - the built-in lease mechanism is the key to providing this functionality. While under normal circumstances
