I am following this wiki to setup some performance numbers for my testing I am doing. I needed to setup graphite to see my numbers.
So I ran this command as mentioned in the wiki on my mac -
docker run -d --name graphite -p 80:80 -p 2003-2004:2003-2004 -p 2023-2024:2023-2024 -p 8125:8125/udp -p 8126:8126 graphiteapp/graphite-statsd
Below is what I got:
> docker run -d --name graphite -p 80:80 -p 2003-2004:2003-2004 -p 2023-2024:2023-2024 -p 8125:8125/udp -p 8126:8126 graphiteapp/graphite-statsd

Now I ran my program which is pushing my metrics to graphite and then I was trying to configure my grafana dashboard by launching grafana docker container with below command as shown in that same wiki:
docker run -d --name -p 3000:3000 grafana grafana/grafana
But I got an error once I executed above command:
> docker run -d --name -p 3000:3000 grafana grafana/grafana
Unable to find image '3000:3000' locally
docker: Error response from daemon: pull access denied for 3000, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
This is the first time I am working with docker so have some issues setting it up and I have already installed docker on my mac. Any idea what is wrong here?
To explain the problem in your command.
Your command
docker run -d --name -p 3000:3000 grafana grafana/grafana
As you can see, --name, no value is specified and that's why it is picking up random value for the image. Use the below command. Meaning of the flags are
--name => Name of the container which is grafana in this case
-p => Publish a container's port(s) to the host, which is 3000:3000 over here
-d => Run container in background and print container ID
docker run -d -p 3000:3000 --name grafana grafana/grafana
Logs of the command:
docker run -d -p 3000:3000 --name grafana grafana/grafana

I have index.html file in a folder. I am mapping the local directory into the nginx docker container.
When I run the nginx docker container using the command
docker run --name website -v C:\Users\prash\Documents\Programming\Spring\Docker:/usr/share/nginx/html:ro -d -p 8080:80 nginx:latest
The container starts successfully but when I run the following two commands in bash, although the container starts, I can't open index.html file in browser.
docker run --name website -v $(pwd):/usr/share/nginx/html:ro -d -p 8080:80 nginx:latest
What might be the issue here?
I am new to docker, I tried finding the solution for this, but couldn't find anything.
After I devise a Spring Boot project with the usage of MinIo, I tried to run it in Docker but I have an issue.
Here is my docker-compose.yaml file
version: '3.8'
services:
minio:
image: minio/minio:latest
container_name: minio
environment:
MINIO_ACCESS_KEY: "minioadmin"
MINIO_SECRET_KEY: "minioadmin"
volumes:
- ./data:/data
ports:
- 9000:9000
- 9001:9001
I firstly run this command docker-compose up -d.
Then I run docker ps -a to check if it is located in container. After that, I run this command docker run <container-id> (a07fdf1ef8c4), here is a message shown below.
Unable to find image 'a07fdf1ef8c4:latest' locally
docker: Error response from daemon: pull access denied for a07fdf1ef8c4, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
I also run this option shown below nothing changed.
C:\Users\host\IdeaProjects\SpringBootMinio>docker run -p 9000:9000 9001:9001 minio/minio:latest
Unable to find image '9001:9001' locally
docker: Error response from daemon: pull access denied for 9001, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
Even if I run the command docker login, I couldn't fix it.
How can I solve it out?
1st Error
docker run <container-id> - That is not how you run a container with Docker. When you run docker-compose up -d, it already starts the containers; in this case it's MinIO.
The docker run function requires an image name as the argument. So when you do docker run <container-id>, it tries to find an image with the container ID, which doesn't exist.
So when you do docker-compose up -d, it starts minio. You do not need to start it again.
2nd Error
When you run docker run -p 9000:9000 9001:9001 minio/minio:latest, you are basically saying that the image name is 9001:9001. But no such image exists. If you want to expose another port, just do docker run -p 9000:9000 -p 9001:9001 minio/minio:latest. For every single port you want to expose, just do -p and enter the port mapping.
I am using docker to run my Keycloak server in aws production environment. The problem is keycloak uses wildfly which is constant running. Because of this I cannot close the shell. I am trying to find a way to run docker as a daemon thread.
The command I use to run docker
docker run -p 8080:8080 jboss/keycloak
Just user docker's detach option -d.
docker run -p 8080:8080 -d jboss/keycloak
I can start elasticsearch with Kibana using the following 2 docker commands...
docker run -d -p 9200:9200 -p 9300:9300 --name elasticsearch-pb elasticsearch
docker run -d -p 5601:5601 --name kibana-pb --link elasticsearch-pb:elasticsearch -e ELASTICSEARCH_URL=http://elasticsearch:9200 kibana
But how do I start es with script support using docker?
Usually this is done by adding 2 lines to elasticsearch.yml file.
script.inline: on
script.indexed: on
how do I change the config file within docker image?
Build a custom image that includes those options.
Create a directory for your docker image
mkdir my_elasticsearch
cd my_elasticsearch
Create an elasticsearch.yml with all the options including
script.inline: on
script.indexed: on
Create a Dockerfile that copies the config file.
from elasticsearch
copy elastcsearch.yml /container/path/to/elasticsearch.yml
Build and tag the image
docker build -t my/elasticsearch .
Then run your image
docker run -d -p 9200:9200 -p 9300:9300 --name elasticsearch-pb my/elasticsearch
You might want to publish your image to the Docker Hub or another registry so you only need to build it once.
You can also use docker-compose to manage the build process and multiple containers.
One approach is to create your own elasticsearch image, through a Dockerfile starting with the official elasticsearch image.
FROM elasticsearch:5
COPY myconfig /path/to/elasticsearch.yml
That way, your image can start an elasticsearch container with the right configuration pre-setted.
I have found a docker image devdb/kibana which runs Elasticsearch 1.5.2 and Kibana 4.0.2. However I would like to pass into this docker container the configuration files for both Elasticsearch (i.e elasticsearch.yml) and Kibana (i.e config.js)
Can I do that with this image itself? Or for that would I have to build a separate docker container?
Can I do that with this image itself?
yes, just use Docker volumes to pass in your own config files
Let say you have the following files on your docker host:
/home/liv2hak/elasticsearch.yml
/home/liv2hak/kibana.yml
you can then start your container with:
docker run -d --name kibana -p 5601:5601 -p 9200:9200 \
-v /home/liv2hak/elasticsearch.yml:/opt/elasticsearch/config/elasticsearch.yml \
-v /home/liv2hak/kibana.yml:/opt/kibana/config/kibana.yml \
devdb/kibana
I was able to figure this out by looking at your image Dockerfile parents which are: devdb/kibana→devdb/elasticsearch→abh1nav/java7→abh1nav/baseimage→phusion/baseimage
and also taking a peek into a devdb/kibana container: docker run --rm -it devdb/kibana find /opt -type f -name *.yml.
Or for that would I have to build a separate docker container?
I assume you mean build a separate docker image?. That would also work, for instance the following Dockerfile would do that:
FROM devdb/kibana
COPY elasticsearch.yml /opt/elasticsearch/config/elasticsearch.yml
COPY kibana.yml /opt/kibana/config/kibana.yml
Now build the image: docker build -t liv2hak/kibana .
And run it: docker run -d --name kibana -p 5601:5601 -p 9200:9200 liv2hak/kibana
