kandi X-RAY | manger Summary
The Manger Node.js package provides caching for RSS and Atom formatted XML feeds, it implements an interface to query entries by feed and time. The obvious challenge here is to build a resilient system facing potentially misconfigured servers and malformed feeds. Most of Manger’s API is implemented as streams. Manger leverages the lexicographical key sort order of LevelDB. The keys are designed to stream feeds or entries in time ranges between now and some user defined point in the past.

I have been trying to use Secret Manager in the lambda function in AWS.
I am using Secret Manager to store my Redshift credentials and want to use the sample code given by the AWS Secret manager to retrieve the secret via the lambda function.
I have set up a Secret in secret manager which contains my redshift credentials (username, password)
I am trying to set up a lambda function which would get the secrets from Secret Manger: below is the sample code:

All my GCP containers use CloudBuild
on my-dev-project
and access secret manager
on the same project (my-dev-project
). However, one project requires access to secrets manger
on my-prod-project
. I imagine I need to add a service account, but I'm not sure how I can go about doing that for CloudBuild
when it already has it's my-dev-project
service account.
Question: How can I access my-prod-project
secret manger
from the my-dev-project
CloudBuild
?
ANSWER
Answered 2021-May-17 at 15:53You can grant the Cloud Build service account from my-dev-project

QUESTION
I have came across a question in docker associate exam test, I found two different answer of the same question on two different platform. So, I wanted to know what is really true about creating overlay network.
One platform mentioned option#1 as correct answer, Overlay network is first created on manger nodes then they are created on the worker nodes once a task is scheduled on the specific worker node.
Another platform mentioned option#3 as correct answer, overlay network are created on all cluster nodes when you create an overlay network.
I found details about ingress network on docker documentation that ingress network is getting created automatically when create a swarm or join any node to the swarm. But I could not find more details on docker website which can answer this question. Any suggestion or reference will be appreciated !
...ANSWER
Answered 2021-Mar-31 at 05:59Option#1 is correct. A network is initialy created on manager nodes and will be created on a worker node once a container attached to this network is deployed on it.
Try it yourself:
- create an overlay network on one of the a manager nodes
- inspect all manager nodes and verify that the network exist on them
- inspect all worker nodes and verify that the network does not exist on them
- deploy a service using a placement constraint that forces the task (which creates the container) to be executed on a particular node; then inspect the worker nodes again to verify that the network is only created on the worker nodes matching the placement constraint

QUESTION
According to my current understanding, all the client connections are authenticated at two levels, channel level and queue manger level,
At the queue manager level, it uses the CONNAUTH
property's value of the QMGR
which is an AUTHINFO
object to determine how the authentication is done (Ex: Using host OS user repo), if the AUTHINFO
object specifies ADOPTCTX(YES)
, it uses the user id contained in MQCSP
structure as the user id for the application context and it is used for authorizations or if ADOPTCTX(NO)
is there, the user id which the client application is running under is used as user id for the application context and that user id is used for authorizations.
At channel level, nothing regarding to authorizations is done. Only the authentication happens there as configured. For more granular access control, a set of channel authentication records are applied to the channels. CONNAUTH
property's value of the QMGR
is still used to determine the user repository to authenticate against.
Questions:
- Am I correct up to this point? (corrections/explanations are much appreciated.)
- What does the MCAUSER attribute of the channel object do? What is the purpose of it? Why does it matter which user the message channel agent runs under?
- After all, how does the channel level authentication actually work with the MCAUSER?
- In what order these two authentication procedures are done? Is the channel authentication done first?
ANSWER
Answered 2021-Mar-14 at 10:40You are correct that one should think about security of client connected MQ applications in two phases. There is an authentication phase (who are you? prove it!), and an authorization phase (now that I know who you are, are you allowed to do what you are trying to do?).
Authentication of a client connected MQ application can be done by checking the user id and password provided by the application (in the MQCSP) or by something at the channel level. This is essentially authenticating the channel connection, but it is inextricably linked to the client application. This channel authentication can use TLS certificates or a security exit to interrogate the remote party any way you feel like. [There is also IP address filtering but I wouldn't call that authentication so much].
The purpose of these authentications are to determine who the connecting party is (and reject them if necessary!) and to assign an appropriate user ID for the next step (the authorization checks). Assignment of this user ID can be done by accepting the password validated user ID (ADOPTCTX(YES)
); by mapping certificate DNs (or IP addresses) using CHLAUTH
rules; by setting the MCAUSER
via a security exit; or by simply hard-coding a user ID into the MCAUSER
(not authentication, but still a way to assign a user id for the later authorization checks). All of these have one thing in common, what they do ends up in the running SVRCONN
's MCAUSER
field. You can display it using DISPLAY CHSTATUS
.
Authorization of a client connected MQ application happens just as it does for a locally bound MQ application. The same operations are checked against the same rules. Is this user allowed to "Open this Queue for putting", or "Inquire this QMgr object", or "subscribe to this topic" etc. The difference is simply in how the user ID used in that authorization check is obtained - i.e. how it gets into the MCAUSER
.
To wrap up (and check I have covered all your questions):-
- Sort of - read above text
- The
MCAUSER
attribute at run-time holds the finally determined user ID for this client application. At definition time it can be hard-coded to a user id (some people use this to hard-code a rubbish user id as a belt-and-braces along side theCHLAUTH
backstop rule). - Channel level authentication essentially sets the run-time value of
MCAUSER
- Authentication happens before authorization.

QUESTION
Is it possible to use an SSIS Cache manger with anything other than a Lookup? I would like to use similar data across multiple data flows.
I haven't been able to find a way to cache this data in memory in a cache manager and then reuse it in a later flow.
...ANSWER
Answered 2021-Mar-01 at 21:25Nope, a cache connection manager was specific to solving lookup tasks originally only allowing an OLE DB Connection to be used.
However, if you have a set of data you want to be static for the life of a package run and able to be used across data flows, or even other packages, as a table-like entity, perhaps you're looking for a Raw File. It's a tight, binary implementation of the data stored to disk. Since it's stored to disk, you will pay a write and subsequent read performance penalty but it's likely that the files are right sized such that any penalty is offset by the specific needs.
The first step you will need to do is define the data that will go into a Raw file and connect a Raw File Destination. Which is going to involve creating a Raw File Connection Manager where you will define where the file lives and the rules about the data in there (recreate, append, etc). At this point, run the data flow task so the file is created and populated.
The next step is everywhere you want to use the data, you'll patch in a Raw File Source. It's going to behave much as any other data source in your toolkit at this point.
