To list docker compartments, we use 'docker holder ls' or 'docker ps' order. The two orders have similar banners as the two orders work on the same thing for example compartment. It has various banners to get the result according to our necessity as it just shows showing compartments to default. The 'docker ps' order is faster and simpler to type.

We need to utilize the Docker CLI apparatus to execute the order to list the holders.

We have two Docker orders that rundown the compartments.

The first is 'docker compartment ls' and the subsequent one is 'docker ps'.

Assuming we run any of this order we just get the running holders on that host, nonetheless, the order has various choices that we can indicate to get the rundown of compartments that we want.

We have numerous holders in various states like a few compartments are running and some are in left status or some other state other than running. We need to list every one of the holders whether or not it is running.

a. How about we make a couple of snow capped compartments as beneath:

b. Now, we can run either ‘docker container ls’ or ‘docker ps’ command to get the list of the containers as below:

We have created 3 containers but both commands show only 1 container as by default it shows only running containers.

c. We have to use the ‘–all’ or ‘-a’ flag to list all the containers as below:

$docker container ls --all
$ docker container ls –a
$docker ps --all
$docker ps -a

Let’s assume we have hundreds of containers running on a host and we want to see specific containers, for example, all containers that are exited, have a specific name, id, label, volume, network, etc.

a. Create few containers with labels and names as below:

b. Let’s start filtering these containers with id first as below:

$ docker container ls -a -f "id= ebe9557e"

c. We can also filter on the basis of the name of the container as below:

$docker container ls -a -f "name=test-con1"

d. We can filter the container based on its labels as below:

In the above snapshot, the first command shows the containers which have label 'type=db' and the second command shows the containers which have label “type” as key regardless of the value.

e. We can filter the containers based on its image as below:

$ docker container ls -a -f ancestor=alpine

$ docker container ls -a -f ancestor=3fd9065eaf02

f. We want to filter containers running before and after a specific container, we can use before and since filter as below:

$ docker container ls -a -f before=laughing_carson

$ docker container ls -a -f since=laughing_carson

There are other filters available as well.

Get familiar with the utilization of the '- design' choice. To show a particular field of the holder or arrangement the result according to our need. We can design in light of compartment ID, picture ID, order, ports, and so on.

a. To show just holder's ID, then, at that point, use - design choice as underneath:

$docker container ls -a --format "{{.ID}}"

b. If we want to output name with the id then we have to add that field as below:

$docker container ls -a --format "{{.ID}} {{.Names}}"

c. We can use the ‘\t’ to make more room between the fields as below:

$ docker container ls -a --format "{{.ID}} \t {{.Names}}"

d. We can use multiple fields at the same time and any symbol if you want as shown below:

$docker container ls -a --format "{{.ID}} -> \t {{.Names}} -> \t {{.Status}}"

e. We can check labels or any other hidden fields that is not shown by default when we list the containers:

$ docker container ls -a --format "{{.ID}} \t {{.Names}} \t {{.Labels}} \t {{.Size}}"

In the above snapshot, only one container has a label i.e. type=db.

f. We can see that the output does not have column headers like ID, Name, Label, etc. We have to use the ‘table’ directives as below:
