When i execute the nerdctl command on terminal with (&) to run in the background , i could get back to the prompt with an "enter" but the same is not working when i put the nerdctl command in scripts. Is there a way to solve this ?
nerdctl run --rm --name Test --env "KEY_FILE=key.pem" --env "CERT_FILE=cert.pem" --env "CA_FILE=ca.pem" --env "CONFIG_FILE=config.json" --env "GNMI_PORT=10164" -p "10164:10164" -v "/root/cfg:/conf" go-sim:21.11.2 &
Thanks in advance.

I've registered a GitLab Runner with shell executor installed on Ubuntu 18.04, and also set up a docker container with the command below
docker run -it --gpus '"device=0"' --net=host -v /home/autotest/Desktop/ai_platform:/app --name=ai_platform_system nvcr.io/nvidia/pytorch:20.10-py3 "bash"
Then I tried to execute the following command from the gitlab-ci.yml in Gitlab CI, but I got an error "The input device is not a TTY".
docker attach ai_platform_system
Any clues for this issue except using docker exec? I know docker exec works in Gitlab CI environment but it will create a new session in the container which is not desirable for me. Thanks!
According to this answer (for Jenkins but the same problem) you need to remove the -it flag and the tty.
docker run -T --gpus '"device=0"' --net=host -v /home/autotest/Desktop/ai_platform:/app --name=ai_platform_system nvcr.io/nvidia/pytorch:20.10-py3 "bash"
I'm currently working on a simple project which is accessing the Github API.
PostgreSQL is used only to get more familiar with it.
I encountered a problem when trying to run the migration scripts from a makefile. This issue does only occur when I'm using make, by applying the migration scripts manually works fine.
The idea is to do this when running "make install":
Start the PostgreSQL container
Run migration scripts
Stop & remove the container
include ./config/dbConfig.env
all: install
.PHONY: all
install :
#runns all migration script. To run a specific migration version build more targets.
#echo "Get latest https://github.com/golang-migrate/migrate image"
docker pull migrate/migrate
#echo "Starting postgreSQL database"
docker run -t -d \
--name dev \
--env-file $(shell pwd)/config/dbConfig.env \
-p 5432:5432 \
-v $(shell pwd)/postgres:/var/lib/postgresql/data postgres
#echo "Wait for database"
sleep 5
#echo "Sun migration scripts"
docker run \
-v $(shell pwd)/migrations:/migrations \
--network host migrate/migrate \
-path=/migrations/ \
-database "postgres://${POSTGRES_USER}:${POSTGRES_PASSWORD}#localhost:5432/?sslmode=disable" up
# for specific migration: ....432/?sslmode=disable" up {{add integer migration number}}
#echo "Stop and remove PostgreSQL container"
docker stop `docker ps -aqf "name=dev"`
docker rm `docker ps -aqf "name=dev"`

Why am I unable to connect to the server from the makefile but if I run the same procedure manually it works? Do you maybe have any ideas about why the behavior is not consistent?
I'm using Docker to running automated browser testing using nightwatch.js
When I open an interactive terminal it works fine, e.g.
docker run -it --rm username/image-name /bin/bash
that gives me a bash prompt and I run:
xvfb-run node nightwatch.js
and everything works fine.
But when I run:
docker run --rm username/image-name xvfb-run node nightwatch.js
It just hangs.
What's the difference between opening a bash terminal and manually running the test command, and just running the test command directly? Surely they should both work?
Ok so I still don't know what is causing this issue, but I have a workaround that works quite well:
Run bash as a daemon:
CONTAINERID=$(docker run -it -d username/image-name /bin/bash)
Then use docker exec:
docker exec $CONTAINERID xvfb-run node nightwatch.js
Of course you will need to do some tidying up afterwards:
docker stop $CONTAINERID
docker rm $CONTAINERID
I am currently learning to use docker to run selenium tests.
However, to run tests on different versions of the browser, it requires creating our own image.
I tried few ways but failed to run them.
I used the docker file at below path:
https://hub.docker.com/r/selenium/node-chrome/~/dockerfile/
and tried to build the image by using the following command:
docker build -t my-chrome-image --build-arg CHROME_DRIVER_VERSION=2.23 --build-arg CHROME_VERSION=google-chrome-beta=53.0.2785.92-1 NodeChrome
Can anyone guide me on how to implement the same?
Regards,
Ashwin Karangutkar
Use
docker build -t my-chrome-image --build-arg CHROME_DRIVER_VERSION=2.23 --build-arg CHROME_VERSION=google-chrome-beta <path_to_Dockerfile>
I am using elgalu/selenium.
docker run -d --name=grid -p 4444:24444 -p 5900:25900 --shm-size=1g elgalu/selenium
And looking in elgalu looks like you can change the browser versions.
Adding -e FIREFOX_VERSION=38.0.6 to the docker run command.
updated: added the missing docker attach.
Hi am trying to run a docker container, with -dti. but I cannot access with a terminal set to dumb. is there a way to change this (it is currently set to xterm, even though my ssh client is dumb)
example:
create the container
docker run -dti --name test -v /my-folder alpine /bin/ash
docker attach test
apk --update add nodejs
cd /my-folder
npm install -g gulp
the last command always contains ascii escape chars to move the cursor.
I have tried "export TERM=dumb" inside the running container, but it does not work.
is there a way to "run" this using the dumb terminal?
I am running this from a script on another computer, via (dumb) ssh.
using the -t which sets this https://docs.docker.com/engine/reference/run/#env-environment-variables, however removing effects the command prompt (the prompt is not shown)
possible solution 1 remove the -t and keep the -i. To see if the command has completed echo out a known token (ENDENDEND). ie
docker run -di --name test -v /my-folder alpine /bin/ash
docker attach test
apk --update add nodejs;echo ENDENDEND
cd /my-folder;echo ENDENDEND
npm install -g gulp;echo ENDENDEND
not pretty, but it works (there is no ascii in the results)
Possible solution 2 use the journal, docker can log out to the linux journal, this can be gathered as commands are executed in the container. (I have yet to fully test this one out. however the log seems to be a nicer output of what happened)
update:
Yep -t is the problem.
However if you want to see the entire process when running a command, maybe this way is better:
docker run -di --name test -v/my-folder alpine /bin/ash
docker exec -it test /bin/ash
finally you need to kill the container after all jobs finished.
docker run -d means "Run container in background and print container ID"
not start the container as a daemon
I was hitting this issue on OSx running docker, i had to do 2 things to stop the terminal/ascii/ansi escape sequences.
remove the "t" option on the docker run command (from docker run -it ... to docker run -i...)
ensure to force bash or sh shells used on osx when running the command from a script file, not the default zsh
Also
the escape sequences were not always visible on the terminal
even so, they still usually caused content corruption, even with SED brought to bear
they always were shown in my editor
