Introduction
I am Akshay Rao working in Annotation.Inc.I tried different container manipulations in this blog. I had written the blog on basic manipulation. I will leave the link of the previous in the conclusion.I have used Go app for demonstration purposes.
How to Restart a Container
Here there can be two situations
To restart a stopped or killed container we can use container start command
docker container start “identifier”
docker container start akshay_rao
akshay_rao
akshayrao@HL00802 ~ % docker container ls -a

docker conatiner restart “indentifier”
docker container restart akshay_rao
akshay_raoHow to Create a Container Without Running
docker container create “image-name”
docker container create -p 8080:8080 aksrao1998/first-go-project
6360b3c15f34b8dc605079cfd1c58f9e4ea9c900d4307bab5fafe766c4623451How to Remove Dangling Containers
Container rm command is used when un-necessary container are there.
docker container rm “container-identifier”
There is also option —rm for container run and container start commands which will remove the containers as soon as they are stopped.
docker container run —rm -p 8080:8080 —name remove_it aksrao1998/first-go-project
How to Run a Container in Interactive Mode
Sometimes we have to execute commands inside the container, -it option is used to get access to the STDERR. Any interactive program inside a container can be interacted with using the -it option. This choice is actually the combination of two distinct choices.
<li>You can send inputs to bash by connecting to the container's input stream using the -i or —interactive option.</li>
<li>By allocating a pseudo-tty, the -t or —tty option ensures that you receive good formatting and a native terminal-like experience.</li>
How to Work With Executable Images
The program running inside the container is isolated from the local host file system so to grant direct access used bind mounts.
By using a bind mount, you can create a two-way data connection between the contents of one directory (the source) on your local file system and another directory inside a container (destination). The source directory will benefit from any modifications made to the destination directory in this manner, and vice versa.
—volume or -v “”local file system directory absolute path:”container file system directory absolute path”:”read write access”
Conclusion
I have covered most of the container manipulation.
