I have a docker image I'd like to poke inside. How can I pull it and get access to a shell on it? I tried sudo docker exec -it verdverm/pypge-experiments bash, but it just gave me Error response from daemon: No such container: verdverm/pypge-experiments. What am I doing wrong?
Replace exec with run:
sudo docker run -it verdverm/pypge-experiments bash

im trying to enter my redis container with this command :
docker container exec -it tgd-api_redis_1 /bin/sh
and this
docker exec -it tgd-api_redis_1 /bin/sh
but the result is error just like the title. i run docker ps to show what container I have, and the container i go to is there.
thanks in advance
Your container names are wrong.
Check stroke and underscore in your names!
Try the container id.
docker exec -it 6a0285dcd25b /bin/sh
To understando how to work the commands on docker, i tried create containers without the run command, but it dont work.
I create a container
$ docker create <image id>
so, i tried to start
$ docker start <container id>
and this return the container id. So, i exec this command
$ docker exec <container id> sh
what generate the error:
Error response from daemon: Container 985547c13d7e3434cc32c0c8bdb1b26fd76ebc95771bc55588866b170852e747 is not running
So, how to create a container and exec a shell to attach ( $ docker attach ) without use run command? The create command seens useless if we cant start and exec on follow.
I think you need to do following steps
create image
docker create -t -i <image ID> /bin/bash
start container interactive mode
docker start -a -i <container ID>
Docker is not started even if the subsequent command is executed.
docker pull incendonet/centos7-mono-apache
Even if you check with docker ps, it does not exist.
Please tell me the cause.
Docker will be started after you run below command :
docker run -it -d image-name
docker run -it -d incendonet/centos7-mono-apache
docker pull command just fetches image from docker hub to your server/local machine. But to run it you need to use docker run.
Once it is running then it will be shown in your docker ps command and you can use below command to get into container's shell :
docker exec -it <container-id> /bin/bash
I'm working through the BlueData docs to enable Kibana.
To start Kibana:
Login to the Controller.
Execute the command docker exec -it monitoring-<controller_ip> bash, where <controller_ip> is the IP address of the Controller.
...
I've ssh'd into my BlueData controller and run the docker exec ... command, however, I get the following error:
Error response from daemon: No such container: monitoring-10.1.0.26
Any idea what is wrong here?
NOTE: My BlueData version is bluedata-epic-entdoc-minimal-release-3.7-2207
First, check what containers are running:
$ docker ps
CONTAINER ID IMAGE ... NAMES
60287e139b54 epic/webhdfs:1.0 ... epic-webhdfs-10.1.0.26
90f73bb7a37e epic/monitoring:1.4 ... epic-monitoring-10.1.0.26
a55758993978 epic/nagios:1.5 ... epic-nagios-10.1.0.26
309d9084df5a epic/apache-hdfs-centos:2.7.2 ... epic-apache-hdfs-centos
You can now see the correct command:
$ docker exec -it epic-monitoring-10.1.0.26 bash
The documentation appears to be missing the epic- suffix, i.e.
Instead of ...
$ docker exec -it monitoring-<controller_ip> bash
It looks like it should be ...
$ docker exec -it epic-monitoring-<controller_ip> bash
I am using docker run --rm -it -v $(pwd):/app composer/composer:1.1-alpine install. But, I need to execute some Bash codes before that, how can I achieve that?
You can enter a running container by running the command:
docker exec -it <container-name> sh
