I am following the instructions for the custom-vision service on raspberry-pi on IOT edge.
I have reached step 3, where in VS Code I am executing Build and Push to IOT Edge Solution and this is triggering the following command:
docker build --rm -f "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/CameraCapture/arm32v7.Dockerfile" -t registry.hub.docker.com/v1/repositories/myname/iot-hub-1/cameracapture:0.2.7-arm32v7 "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/CameraCapture"
&& docker push registry.hub.docker.com/v1/repositories/myname/iot-hub-1/cameracapture:0.2.7-arm32v7
&& docker build --rm -f "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/ImageClassifierService/arm32v7.Dockerfile" -t registry.hub.docker.com/v1/repositories/myname/iot-hub-1/imageclassifierservice:0.2.4-arm32v7 "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/ImageClassifierService"
&& docker push registry.hub.docker.com/v1/repositories/myname/iot-hub-1/imageclassifierservice:0.2.4-arm32v7
Which is failing with 404 - page not found.
I also tried using cloud.docker.com/repository/registry-1.docker.io/myname/iot-hub-1 but this gave me a different error:
invalid argument
"cloud.docker.com/repository/docker/myname/iot-hub-1:latest/cameracapture:0.2.7-arm32v7"
for "-t, --tag" flag: invalid reference format
Can anyone assist with the correct URL path, or some the additional steps i need to uploading the containers to my docker hub repository?
I couldn't find the correct URL for dockerhub, but Azure Container Registry was able to resolve my problem.
Details of the URL are here: Raspberry PI / IOTEdge failing to pull from Azure Container Registry
You need docker login first. Then build image docker build -t <docker_hub_username>/<app_name>:<tag> and then just push docker push <docker_hub_username>/<app_name>:<tag>. You don't need to specify any specific URL for Docker Hub.
Use this:
docker push <hub-user>/<repo-name>:<tag>
i.e
docker push username/reponame:latest
From the docker quickstart terminal on Windows 7 64-bit, I'm following the instructions to install this docker container. I run the command,
docker run http://wiki.openstreetmap.org/wiki/nominatim
and I get this error:
c:\program files\docker toolbox\docker.exe: invald reference format.
I can't find any information about this error related to this container.
You need to pull the image first , then run the container. according to your docker command, you are trying to access a website, it is not a docker container image. so that's why it is giving you the invalid reference format.
The image name that you have specified to pull and run is wrong. The image name should be mediagis/nominatim.
Your docker run command should be
docker run mediagis/nominatim
It is not necessary to pull the image first and run it. By default docker run first tries to find such image in your machine if not then it tries to download from docker repository.
If you specify URL format it directly downloads from private repo if such image is not found in your machine.
Brief Explanation:
Docker takes whatever that is in form of url as an image and the reason for this is sometimes you may want to run image from your private repository. So here http://wiki.openstreetmap.org/wiki/nominatim is considered as an image called wiki/nominatim from a private repo called wiki.openstreetmap.org by docker and the format of private repo and image is wrong . It should be <domain.com>/image:tag where tag is optional. You are not supposed to provide protocol (http://). See this for reference Hence the error is thrown as invalid reference format.
If you would have given as docker run wiki.openstreetmap.org/wiki/nominatim it would have tried to download image called wiki/nominatim from wiki.openstreetmap.org private repo with latest tag. Since no such repo and image exists it reports Error response from daemon: error parsing HTTP 404 response body as the url throws 404: Not Found when docker daemon tries connecting to it.
References:
Pull an image from Docker Hub
Pull from a different registry
docker run
Docker run reference
Note: Unless you specify tag name which is optional docker always downloads latest tag from repo.
docker run http://wiki.openstreetmap.org/wiki/nominatim
does non make any sense syntactically ...
In any case the correct command to get the latest image is:
sudo docker pull mediagis/nominatim:3.1
Notice that each version has its own installation instructions (versions prior to 3.1 were structurally different), so please do refer to the appropriate section:
https://hub.docker.com/r/mediagis/nominatim/tags/
However I do agree with you that
docker run --restart=always -p 6432:5432 -p 7070:8080 -d -v /home/me/nominatimdata/postgresdata:/var/lib/postgresql/9.5/main nominatim sh /app/start.sh
Should be
docker run --restart=always -p 6432:5432 -p 7070:8080 -d -v /home/me/nominatimdata/postgresdata:/var/lib/postgresql/9.5/main mediagis/nominatim sh /app/start.sh
instead. The installation instructions need updating there.
I issued a command "docker build -t httpd ."from bash with preconfigured docker file having
FROM httpd.latest .
Once command is executed and after step 1 it says "pull access denied for httpd.latest, repository does not exist or may required docker login.
Yes , image which you are using might not exixts in public dockerhub
First search image using
docker search httpd
If you can find that then you need to create on
https://github.com/docker-library/httpd/blob/c14a031c014aa2219aea2e73786f577300756f0b/2.2/Dockerfile
In your dockerfile use
FROM httpd
not latest,
docker will pull latest image if tag is not specified or use specific version
New to docker and I'm using Windows 7 SP1. It looks like docker is running fine in my machine as I have tried running hello-world by command docker run hello-world as instructed in the tutorial and got expected result. Now all I'm trying to do is create a docker image for a .net core console app. My app built and ran. but while building docker image by command docker build -t myapp . I get the below error
error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&c

Below my Dockerfile
FROM microsoft/dotnet:1.1-runtime-nanoserver
WORKDIR /DotNetConsole
COPY /bin/Debug/netcoreapp1.1/publish/ .
ENTRYPOINT ["dotnet", "DotNetConsole.dll"]
I could get around this problem by starting the "Docker QuickStart Terminal" installed with the docker tools, and running the commands for building the docker images from there.
If I used GIT BASH instead of the Docker QuickStart Terminal to execute the commands, I would get this kind of error. So it seems that if the commands are not executed from the Docker terminal itself, these errors show up.
I have created a simple docker file to deploy a war in tomcat
FROM tomcat
ADD your.war /usr/local/tomcat/webapps/
CMD ["catalina.sh", "run"]
I tested locally and works. I tried building the image and pushed it to Bluemix. The docker image got pushed and I can see it in the dashboard, but while trying to start it up (By Clicking on it ), the Vulnerability assessment kicks off and it gives a warning symbol with an Incomplete text and I am unable to proceed further. Need pointers on how to go about this.
Steps followed -
From my local m/c where I have docker running
# docker tag testimagetom registry.ng.bluemix.net/shabsctr/testimagetom:image_tag
# docker push registry.ng.bluemix.net/shabsctr/testimagetom:image_tag
# cf ic run --name shabstrydocker registry.ng.bluemix.net/shabsctr/testimagetom:image_tag
You can build images with DockerFile by cf command. It'll create your image on your bluemix registory.
cf ic build [--tag|-t TAG_NAME] [--no-cache] [--pull] [--quiet] LOCAL_DOCKER_FILE_PATH
