Hello,
How to install a docker for Microservices. I tried to install it on my home laptop but it failed as it requires Windows 10 pro.

Regards

I have a server that has 32GB of RAM and 8TB of HDD with RAID 1 for 4TB of total HDD space.

I would like to split that with 2 TB being NFS and 2TB being Samba.

This is sort of a discussion oriented question.

I was wondering about running NFS and Samba under LXD or Docker containers. Would there be advantages to doing this (at least for learning)?

Hi Experts,

I get the following error when I run the docker

root@ip-10-252-14-11:/home/ubuntu/workarea/sourcecode/NTDL-TEST/Harvest-Trove-Pictures# sudo docker start trove_pull
Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"start\\\": executable file not found in $PATH\"\n"
Error: failed to start containers: trove_pull

Hi Experts,

I get a bad gateway when running the web application from docker.

I had installed nginx inside the docker container.

for eg,

docker gateway is 1.2.3.4

public ip is 4.3.2.1

I create the environment for the docker container

declare -a ntdl_environment=( -e ES_CONNECTION=1.2.3.4:9200 -e DATABASE=postgres://user:****@1.2.3.4/ntdl -e LOCAL_URL_PREFIX==https://ntest-dev.s3.amazonaws.com -e IIIF_SERVER=http://4.3.2.1/iiif -e FACEBOOK_APP_ID=000000 -e CLOUD_WATCH=true -e AWS_ACCESS_KEY_ID=akz44 -e AWS_SECRET_ACCESS_KEY=******** -e AWS_DEFAULT_REGION=ap-abct-2 -e S3_BUCKET=abc-test-dev -e GENERIC_SERVER_NAME=http://4.3.2.1 -e SEARCH_PATH=/ -e SEARCH_DOMAIN=http://4.3.2.1 -e HANDLE_SITEMAP_PATH=https://s3-test.amazonaws.com/ntest/sitemap/sitemap.txt.gz -e DEBUG=true)

Select all Open in new window

I had run the following commands to run the docker container

docker run --name ntdl -d --restart always  ${ntdl_environment[@]} f27af16c9ed6

to go inside bash shell for the docker container i had run the follow command from command prompt

docker exec -it ntdl /bin/bash

when I run gateway ip for elasticsearch it is running fine inside docker
I get the following results it is working fine

root@16a1d7df5399:/home/ntdl/code# curl -XGET 1.2.3.4:9200
{
  "name" : "C****D",
  "cluster_name" : "elasticsearch",

    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  },
  "tagline" : "You Know, for Search"
}

I had checked nginx status inside docker it is working fine.

root@16a1d7df5399:/home/ntdl/code# service nginx status
 * nginx is running

curl -XGET 'localhost' inside the docker gets the following below error

I have a java backend application which is containerised using docker. The front end for this application is developed using npm and these static files are deployed in nginx. And it works perfectly. The api calls to the backed is proxy passed to the docker host using nginx reverse proxy.




Now i need to setup docker swarm for this backend application using manager and worker nodes.


So these are the questions which I need to ask you experts,

To which host should I need to configure proxy pass in nginx while using docker swarm?


Thanks in advance :)

Are there any limitations in Linux containers (LXC/LXC/dockers) with regards to supporting software / os etc, vs with full virtualization software or bare metal?

How to download awscli docker image  (I try docker run awscli it ask password without that is it possible)

How to download mariaDB docker image  (I try docker run mariaDB it ask password without that is it possible)

Hi Experts,

     docker container is not picking the recent changes from the source code.     it makes me to build the docker image every time to see the latest changes on the source code.

Please find below the contents of the Dockerfile

What are all the package need to access docker to lambda


lambda will call s3 bucket .

I need automated script (that script will daily mid night will run)

Hi Experts,

   I got a server which runs applications with docker and aws, running from console(putty).  The command to run is as follows:-

docker run --name ts_pull ${ts_environment[@]}  -d  --restart always 1234656458.dkr.ecr.ap-southeast-2.amazonaws.com/harvest-ts:1.0.2 start pull

Select all Open in new window

I can understand 1234656458.dkr.ecr.ap-southeast-2.amazonaws.com/harvest-ts:1.0.2 is from aws.  Can any tell me how this container application is pushed to aws?

From the documentation I found Dockerfile is available, from which the docker image is built.  I don't understand how to push this to aws and run with the docker.

Please throw some light over it.

with many thanks,

Bharath AK
