zCX: Personal and technical Userids mustn't be in the same group / results in workflow failures / rerunability

The zCX workflow says for the SAF group to be specified during provisioning: "Specify an existing SAF group name to allow that group access to this IBM z/OS Container Extensions appliance instance directory. The provisioning user of this IBM zCX a...

sudo incidents should be reported

If a user, that is not in the sudo group tries to issue a sudo it looks like this: user@server:~$ sudo mkdir /test[sudo] password for user:user is not in the sudoers file. This incident will be reported. But as I was told in case TS004442144 this ...

z/OSMF Workflow Syntax Check for input variables

Currently, z/OSMF seems to not be able to check input fields for the correct syntax. In case of wrong input fields, z/OSMF just accepts the input and continues. This is even worse in case of e.g. provisioning a black box like zCX. For example: zCX...

Ability to send message to zOS Syslog from Docker container in zCX

In an attempt avoid custom code running on the z/OS side I'm simply using fluentd to format the messages then write them out to the USS syslog, which in turn is set to write them to the console. They're being written out fine but are all preceded ...

zCX: Allow specification of TZ variable during provisioning / same time zone for all users

zCX: Make docker cli available as MODIFY command to the STC

Currently, we've to login to zCX to issue "docker" commands like docker logs to zCX. In an early phase like POC / testing this is no problem. But as we're continuing / have the first production applications running, Operators also have to work wit...

zCX - Externalize failure information to the joblog

Hello, zCX generates FFDC files when a problem is experienced and in the above case zCX restarted. There is no indication of the nature of the problem in the joblog, just that FFDC dumps were captured and zCX was restarted. We have to open a case ...

Enhance z/OS IP Filtering so that rules can be defined to control access to ports that containers in zCX are listening on

Currently z/OS IP filtering only allows rules to be defined to control access to the TCPIP address that a zCX Instance uses. In a zCX instance, we can run a number of docker containers, each listening on different TCPIP Ports. Each of these contai...

Provide a way to identify zCX address spaces

Customers would like to be able to identify address spaces as zCX running address spaces. Preferably they would like a field on an SDSF screen to say yes or no. Then they can sort of select based on that setting.
