@RomanPerekhrest From the expected output, it looks as if it's intended to be a fixed string.

@Kusalananda, there are many unexpected cases in comprehension of user questions. I feel like it's better to obtain the real "picture" through elaboration (even if something seems simple) (based on experience of working with SO and U&L)

Using standard sed:
sed 's#http://master02.$domain:8080#http://$machine_master.$domain:8080#' file >newfile
This replaces the exact string http://master02.$domain:8080 with http://$machine_master.$domain:8080 and writes the result to a new file.
The $ in $domain has to be escaped to not be interpreted as an "end of line" pattern. The $ in the replacement text does not need to be escaped as this part is not a pattern.
I'm using # as a delimiter for the sed substitute command (s) as the pattern and replacement text both contain / which is the default delimiter.
The command could also be shortened to
sed 's#http://master02#http://$machine_master#' file >newfile
if it's safe to do so (this depends on the contents of the file and what instances of text you'd like to replace).
Testing:
$ cat file
value=master02_up
#master02
http://master02.$domain:8080
$ sed 's#http://master02.$domain:8080#http://$machine_master.$domain:8080#' file >newfile
$ cat newfile
value=master02_up
#master02
http://$machine_master.$domain:8080
