π§ Introduction to Vault Server Operations
This paragraph introduces the setup and basic operations of the Vault server. It explains the process of installing and starting the Vault server in development mode. The main focus is on performing read, write, and delete operations using the command line interface of Vault. The paragraph details the syntax and usage of commands for these operations, including the need to specify the type of secret being stored and the path where it will be stored. It also touches on the concept of a secret engine in the HashiCorp ecosystem and the necessity of enabling custom paths within the secret engine before storing secrets.
π Listing and Deleting Secrets in Vault
This paragraph delves into the commands for listing all available secrets at a specific path and deleting secrets from the Vault server. It starts by explaining how to list the parts defined inside the secret engine, including custom paths and default ones created by the HashiCorp server. The paragraph then describes the command for deleting a previously created secret, emphasizing the success message received upon deletion. To confirm the deletion, it instructs how to use the get command to read the same secret, which should now result in a 'no value found' message, indicating successful deletion.

Transcripts
all right so till now what we have done
so far we have installed the Vault
server and as well as we have started
the Vault server into the development
mode so the next thing which we are
going to do we are just going to perform
some operation using the command line
interface of Vault and the operation
which we are going to perform is the
read write and delete so using this
operation we are just going to insert or
we are just going to write the secret we
are just going to fetch or to read the
secret as well as when we are done with
all this we are just going to delete the
secret which we have written previously
so here on to the screen you can see I
have written some example command for
read write and delete but I'm just gonna
explain each command in more detail
let's start with the First Command that
is the right command and here you will
see the command start with the keyword
world so this is the first thing which
you need to write over here whenever you
are using the command line interface of
your wall the second thing is you need
to Define like what kind of a secret
you're going to store so here we are
just storing the key and value so key K
and V is the abbreviation for a key and
value so that's why you need to mention
what kind of a secret you are storing so
that means you are storing key value
pair
second we are just going to write so
that's why we need to mention put over
here
so that you can ah give the instruction
to our wall that we are just going to
write this secret into our vault server
second you need to define the path where
you are going to store this secret so
this is the path this is a custom path
you can write any path of your choice so
here I have written a path my slash path
so this is the path where our secrets
will be stored all right the next thing
is the actual value and since we are
using the key value pair so we need to
define a key first and then its value so
here you will notice this is the key and
this is the value so this is the key ah
for our secret and this is the value for
our secret so this is the typical syntax
of our Hashi core write or a put
operation there is also one more
important concept of a secret engine in
the hashicorp world so if you notice
over here in this right command we have
mentioned the path over here
this is the path so whenever you specify
a new custom path so this is my custom
path over here so if you are working
with the hashicorp world and if you need
a new custom part then you need to
enable this custom path into the secret
engine I'm just gonna show the command
to enable that so here if you notice
over here so this is the command for
enabling the path for inside your secret
engine so this is the command how it
starts with the Vault then you need to
specify secret then you need to specify
the keyword enable and then you need to
specify the path so this is the thing
which you need to mention inside your
hashicop server so that it can enable
that particular path inside your secret
engine and apart from that you need to
mention what it is so it is a key value
pair kind of for Secrets which you are
planning to store so this is the
important command which you need to run
before you start writing or inserting
your secret let's switch over to the
terminal and is my terminal and the
first thing which I'm just gonna start
I'm just gonna enable the path in my
secret engine so this is the command
which I'm just gonna run so that will
enable the path my
so here you can see this is the
successful message which I got after
that I'm just gonna insert my first
secret key value pair
and here you can see uh success message
and the data written into the path my
slash path now after writing like how to
read the secret from our Hashi curve
fault so here you can see on to the
screen this is the command vault key
value get and the path name so this is
the command which I'm gonna use so I'm
just talking about this command
okay so I'm just gonna get back to my
terminal once again and I'm just gonna
make some space and hit enter and here
you can see I'm just trying to read the
secret stored at my slash path there is
also one more cool feature of our
hashicorp world you can read the secret
in the Json format also and the command
for that is I'm just gonna clear the
screen over here and paste the command
over here so here you can see this is
the output in the Json format so what
you need to do is vault key value get
and you need to specify the format Json
after that the path where your key value
or the secrets has been stored so this
is how you can generate the output in
the Json format as well all right so now
we have seen the right operation we have
seen the read operation and also we have
seen how to enable the path in the
secret engine so the next command which
we are gonna see is the delete command
how we are going to delete the secret
from the world but before that there is
also one more import concept or one more
important command to list all the
available Secrets at particular path
so I'll just go back to my terminal and
I'm just gonna run command Vault secret
list
so here you can see these are the parts
which are defined inside my secret
engine so here you will find my path
also so this is the my custom path which
I have created apart from that these are
the default ones so this is secret this
is this this is identity and this is
Cubby Hole so these are the four the
other four which by default created by
hashicop server and apart from that if
you run this command Vault secret list
then you will find all the available
path which are defined inside your Vault
server so this is how you can run this
command to view or to list all the
secret path available into your
hashicorp server all right let's run the
delete command so that we can delete the
secret which we have created and the
command for that is vault key value that
is KB delete and the path that is my
slash path and it will delete the secret
which we have created previously simply
hit enter and as you can see this is the
success message and the data has been
deleted from my path and just to verify
let's run the get command once again to
read the same secret which we have just
deleted so just simply hit enter onto
your terminal and here you can see no
value found at my slash path that means
we have successfully deleted our key
value secret which we have stored
previously all right so now you know
like how you can read write and delete
the secrets from your hashikov Vault
server in the next session we are going
to talk more about the secret engine and
we will be taking a look how to enable
the AWS secret engine how to enable and
disable the key value pair secret engine
and some more commands to manage the
secret engines
