Unable to go inside a running docker container-CodePudding

I am using ubuntu 22.04 lts as a sudo user.

I made a react application and then I created a image and ran it in a container successfully. But i want to go inside the container for which i ran the below command:

docker exec -it e448b7024af bash

but i got the following error:

Error response from daemon: Container e448b7024af19a0bb is not running

I ran the below command to check if container is running:

docker ps
// i got my container in the list
// also i did some actions in react application to double check if conatiner was working and it worked perfectly

below is the output for the above command:

CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS                                       NAMES
56f8042d2f1   react_d   "docker-entrypoint.s…"   12 minutes ago   Up 12 minutes   0.0.0.0:3000->3000/tcp, :::3000->3000/tcp   youthful_sammet

then based on some other solution i tried the below command:

 docker run -it e448b7024af /bin/bash

and i got the following error:

Unable to find image 'e448b7024af:latest' locally
docker: Error response from daemon: pull access denied for e448b70254af, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

then i tried the following command based on some solution i found:

docker pull e448b7024af:latest

but i got the following error:

Error response from daemon: pull access denied for e448b7024af, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

i also tried:

docker exec -it 568f8042d2f1 bash

and i got the following error:

OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown

Below is my Dockerfile:

FROM node:alpine

WORKDIR /app

COPY /package*.json ./

RUN npm install

COPY . .

CMD ["npm","run","start"]

My container is working properly but i am unable to get inside of the container. Any help is appreciated. Thanks in advance.

CodePudding user response：

Based on the output from docker ps, your container id is 56f8042d2f1 and not e448b7024af which I suspect might be your image id or a container id from a previous run.

Another thing is that bash isn't installed in Alpine images by default. You can use sh instead.

You can use the more human-friendly container name of youthful_sammet in your command and do

docker exec -it youthful_sammet sh

or, if you prefer the id

docker exec -it 56f8042d2f1 sh

CodePudding user response：

you are using the wrong container identifier in the docker exec command as when you do docker ps the container id is different and you are using the wrong one. I personally use the container name as identifier it is easy to remember.
