I am trying to use opentelemtry (OTEL) in akka-http application (Scala), using the stand alone agent.
In my sbt I have this:
fork := true
run / javaOptions ++= Seq(
"-XX:+UseG1GC",
"-XX:MaxGCPauseMillis=100",
"-XX:+PrintGCDetails",
"-XX:+PrintTenuringDistribution",
"-XX:+PrintGCCause",
"-XX:+PrintAdaptiveSizePolicy",
"-javaagent:/myFolder/jars/opentelemetry-javaagent.jar",
"-Dotel.service.name=pantryLocalExecution",
"-Dotel.traces.exporter=otlp",
"-Dotel.metrics.exporter=otlp",
)
envVars += "OTEL_JAVA_GLOBAL_AUTOCONFIGURE_ENABLED" -> "true"
I am using Jeager to watch all metrics that OTEL collects, then thing is, Jeager is not showing Http request, only mysql connections.
Addition to that, is not grouping the flow into the same trace, Next image show what I mean. There are 3 traces which are the same flow.
Thank you all for all your help!!
Quick notes:
I am sure that the agent path is ok.
Before use Jaeger UI i needed to run docker command:
** docker run -d --name jaeger \\n -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \\n -e COLLECTOR_OTLP_ENABLED=true \\n -p 6831:6831/udp \\n -p 6832:6832/udp \\n -p 5778:5778 \\n -p 16686:16686 \\n -p 4317:4317 \\n -p 4318:4318 \\n -p 14250:14250 \\n -p 14268:14268 \\n -p 14269:14269 \\n -p 9411:9411 \\n jaegertracing/all-in-one:1.42\
Finally I run using sbt run command.

I am using K8S
I want to calculate a string that that is a result of kubectl exec -it ... -c
after the -c option there is a string.
How can I pass a string with double quotes inside.
The following example doesn't work properly.
x="$(kubectl exec -it mysql-pod -- /bin/sh -c \"mysql -uroot -p12345
-e 'show databases'\" 2>/dev/null)"
echo $x
Thanks.
when only a command needs to be executed on a pod , -it option is not required as it stands for attaching an interactive teminal
when mysql is itself an executable command , no need to use /bin/sh -c
no need to encapsulate whole command in " "
So try following
x=$(kubectl exec mysql-pod -- mysql -uroot -p12345 -e 'show databases ;' 2>/dev/null)
echo $x
I want to run the cp-schema-registry image on AWS ECS, so I am trying to get it to run on docker locally. I have a command like this:
docker run -e SCHEMA_REGISTRY_HOST_NAME=schema-registry \
-e SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS="1.kafka.address:9092,2.kafka.address:9092,3.kafka.address:9092" \
-e SCHEMA_REGISTRY_KAFKASTORE_SECURITY_PROTOCOL=SASL_PLAINTEXT \
confluentinc/cp-schema-registry:5.5.3
(I have replaced the kafka urls).
My consumers/producers connect to the cluster with params:
["sasl.mechanism"] = "PLAIN"
["sasl.username"] = <username>
["sasl.password"] = <password>
Docs seem to indicate there is a file I can create with these parameters, but I don't know how to pass this into the docker run command. Can this be done?
Thanks to OneCricketeer for the help above with the SCHEMA_REGISTRY_KAFKASTORE_SASL_JAAS_CONFIG var. The command ended up like this (I added port 8081:8081 so I could test with curl):
docker run -p 8081:8081 -e SCHEMA_REGISTRY_HOST_NAME=schema-registry \
-e SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS="1.kafka.broker:9092,2.kafka.broker:9092,3.kafka.broker:9092" \
-e SCHEMA_REGISTRY_KAFKASTORE_SECURITY_PROTOCOL=SASL_SSL \
-e SCHEMA_REGISTRY_KAFKASTORE_SASL_MECHANISM=PLAIN \
-e SCHEMA_REGISTRY_KAFKASTORE_SASL_JAAS_CONFIG='org.apache.kafka.common.security.plain.PlainLoginModule required username="user" password="pass";' confluentinc/cp-schema-registry:5.5.3
Then test with curl localhost:8081/subjects and get [] as a response.
For my project. I want to use flower config file to instead of use command line options.
But I write a file named flowerconfig.py, like follows:
# RabbitMQ management
broker_api = 'http://user:passwd#localhost:15672/api/'
# Enable debug logging
logging = 'DEBUG'
# view address
address = '0.0.0.0'
port = 10006
basic_auth = ["user:passwd"]
persistent = True
db = "var/flower_db"
But when I run flower with the command flower --conf=flowerconfig. I found this broker not work.
I replace the command with celery flower -A celery_worker.celery_app --conf=flowerconfig. celery_worker is my celery file.
the broker is running normally. but still the flowerconfig basic auth not work .enter code here
So I don't know if flower support file config. or other methods.
the versions:
flower==0.9.2
celery==4.2.1
You can create a bash script to run. For example:
#!/bin/bash
celery -A project flower \
--basic_auth=monitor:password \
--persistent=True \
--max_tasks=9999 \
-l info \
--address=0.0.0.0 \
--broker=redis://localhost:6379/0
I try to create a new project based on the meteor with docker.
I found the repository for this:
https://github.com/meteorhacks/meteord
I created Dockerfile and put there
FROM meteorhacks/meteord:onbuild
And then run:
docker run meteorhacks/meteord
docker run mongo
After downloading all packages so finally I run
docker run -i -t 807754a01782 -d
-e ROOT_URL=http://localhost:3000
-e MONGO_URL=mongodb://127.0.0.1:27017/
-e MONGO_OPLOG_URL=mongodb://127.0.0.1:27017/
-p 8080:80 myapp
Based on this example:
docker run -d \
-e ROOT_URL=http://yourapp.com \
-e MONGO_URL=mongodb://url \
-e MONGO_OPLOG_URL=mongodb://oplog_url \
-p 8080:80 \
yourname/app
Inside myapp folder, I have fresh meteor project.
But as a result, I received
> You don't have an meteor app to run in this image.
Can anyone help me and give me some clues what I'm doing wrong? Or I misunderstanding how Docker with this repository works?
EDIT:
The problem was in command correct command is:
docker run -d
-e ROOT_URL=http://localhost:3000
-e MONGO_URL=mongodb://127.0.0.1:27017/
-e MONGO_OPLOG_URL=mongodb://127.0.0.1:27017/ -p 8080:80

But now when I check the status of this container I see it is excited. How Can I check what causing the problem?
I want to create 2 containers of postgrSQL so that one can be used as DEV and other as DEV_STAGE.
I was able to successfully create one container and it is been assigned to port 5432. But when I'm trying to the second container, it is getting created(sometimes shows the status as EXITED) but not getting started because of the port number issue.
The below are the commands which I ran.
sudo docker run -v "pwd/data:/var/lib/pgsql/data:Z" -e POSTGRESQL_USER=user1 -e POSTGRESQL_PASSWORD=password -e POSTGRESQL_DATABASE=test_db -d -p 5432:5432 fedora/postgresql
sudo docker run -v "pwd/data_stage:/var/lib/pgsql/data_stage:Z" -e POSTGRESQL_USER=user1 -e POSTGRESQL_PASSWORD=password -e POSTGRESQL_DATABASE=test_db -d -p 5432:5433 fedora/postgresql
I think the port mapping which I'm using is incorrect. But not able to get the correct one.
You have an error in volume definition of the second container. Don't change path after colon, it is mandatory the path is set to /var/lib/pgsql/data.
Also you fliped ports mapping. The correct command is like this:
sudo docker run -v "`pwd`/data_stage:/var/lib/pgsql/data:Z" -e POSTGRESQL_USER=user1 -e POSTGRESQL_PASSWORD=password -e POSTGRESQL_DATABASE=test_db -d -p 5433:5432 fedora/postgresql
If anything goes wrong inspect container logs with docker logs CONTAINER_ID
Thanks for the answer. I corrected the path. I think flipping the port number will not work too. Because I already have one container which is mapped to 5432. So I can't map the port to 5432 again. The below command with worked for me. First, I modified Postgres default port to 5433 using export variable PGPORT=5433.
sudo docker run -v "`pwd`/data_stg:/var/lib/pgsql/data:Z" -e PGPORT=5433 -e POSTGRESQL_USER=user1 -e POSTGRESQL_PASSWORD=password -e POSTGRESQL_DATABASE=test_db -d -p 5433:5433 fedora/postgresql
