It is not necessary (the final undeploys at the end are "always_exec"),
and makes the CI potentially fail since there is nothing to copy at this
point.
When migrating from RHEL (on cacofonix) to Ubuntu 22.04 (on acamas), the `nc`
command needs to be replaced by `ncat`. The version of `nc` available on Ubuntu
is the OpenBSD variant, which lacks support for some options used in our scripts.
`ncat` from the Nmap is used instead.
With the server object to be passed into ping test, it's not necessary
to either hardcode an IP address or provide a template. Instead, always
fill the IP address, which simplies the Ping() code.
Verify that we don't have an IP address/hardcoded by throwing an
assertion.
This is not really used as of now, because most IPs are hardcoded. See
one of the next commits for the use of this.
To make sure that we have the correct IP, there is some code that
verifies that a hardcoded IP and the CN IP would be the same.
Note: need two separate ci_infra.yaml entries, because
- for FlexRIC, the container name is different (is the tutorial CN)
- for RFsim5G E1, we don't have ext-dn => ping UPF
- pass parameter directly instead of indirectly via class
- harmonize to svr_id to read through common code in the next commits
- pass images to express which images will be deleted
- refactor function to use "with" for cls_cmd, and return success (or
not)
- pass parameter directly instead of indirectly via class
- call it simply "images", to harmonize with clean-function later
- harmonize to svr_id as in the previous commit
- rewrite function to use with-statement with cls_cmd
- optionally pass a tag to use (which will be used in a test, and can be
used to pull flexric)
- Introduce Pull_Image() which does the actual pulling, can pull from
any registry, and will be reused in the case of pulling from cluster.
Use a script, which can be tested independently of CI code (by running
it on the host on which it will be used), and print the directory that
has been prepared in the HTML. Also, in the description, use the
infinitive/imperative(?) of the verb to harmonize with other steps.
